react-native-reanimated [iOS Crash] EXC_BAD_ACCESS in folly::dynamic::hash() via ShadowNode clone

trafficstars

Description

I’m encountering an intermittent crash on iOS when running my React Native app using react-native-reanimated. The crash doesn't happen consistently, but it occurs occasionally during normal usage. It seems related to the native folly::dynamic::hash() call via ShadowNode::clone().

This crash occurs on real iOS devices.

Stack Trace Screenshot

Please find the crash log screenshot below:

Crash Screenshot

Key lines: EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000000 folly::dynamic::hash() const + 490 ShadowNode::clone(facebook::react::ShadowNodeFragment const&) + 144 reanimated::cloneShadowTreeWithNewPropsRecursive(...)

Steps to reproduce

EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000000 folly::dynamic::hash() const + 490 ShadowNode::clone(facebook::react::ShadowNodeFragment const&) + 144 reanimated::cloneShadowTreeWithNewPropsRecursive(...)

This seems to be a native-level crash related to folly::dynamic being used as a key in an unordered map.
I’m not directly using folly, but I believe it's used internally by Reanimated or React Native core.
I suspect a null or improperly initialized dynamic value may be passed during ShadowNode cloning.

Reanimated Setup

Reanimated plugin added in babel.config.js
Ran npx react-native-reanimated patch
Linked properly with CocoaPods (pod install done)

What I've Tried

Cleaned build: npx react-native-clean, xcodebuild clean
Rebuilt the app multiple times
Crash still happens occasionally, only on iOS, not Android

Additional Notes

This seems to be a native-level crash related to folly::dynamic being used as a key in an unordered map.
I’m not directly using folly, but I believe it's used internally by Reanimated or React Native core.
I suspect a null or improperly initialized dynamic value may be passed during ShadowNode cloning.

Request

Please let me know:

If this is a known issue
Any workaround or patch
If I can provide a minimal repro (currently it's hard to reproduce consistently)

Snack or a link to a repository

This issue occurs intermittently on a real iOS device and involves a crash inside native code (folly::dynamic::hash() via ShadowNode::clone). Since the crash involves React Native Fabric internals triggered via react-native-reanimated, it cannot be reproduced in Snack (which does not support native modules or Hermes). Due to the native nature and randomness of this crash, creating a minimal reproduction repo is extremely difficult. However, I’ve attached the crash log screenshot and full environment info to help with investigation.

Hey! 👋

The issue doesn't seem to contain a minimal reproduction.

Could you provide a snack or a link to a GitHub repository under your username that reproduces the problem?

Hey! 👋

It looks like you've omitted a few important sections from the issue template.

Please complete Description section.

Due to the intermittent and native-only nature of the issue, a consistent reproduction is difficult, but here’s what generally happens:

Start the app (with Hermes enabled and using Reanimated 3.17.1)

Navigate between screens that use animated components

Occasionally, the app crashes with a native EXC_BAD_ACCESS in folly::dynamic::hash()

I’ve tried cleaning builds, patching Reanimated, checking for undefined animated props, and verifying proper Reanimated setup — but the crash persists.

EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000000

We're hitting the same issue, affecting ~1 in 10 users. We also have no reliable way to reproduce it so we're currently looking into automating the behavior the seems to cause it in the iOS Simulator (where it also happens), and seeing if ASAN / TSAN provide any additional information.

Here's the relevant callstack from the one time we've managed to catch this in the debugger so far:

From looking at this, it seems that thread T9 is writing into family.nativeProps_DEPRECATED while reanimated is cloning the shadow tree, resulting in a data race inside ShadowNode::clone, which tries to read family.nativeProps_DEPRECATED at the same time (in its if check and the componentDescriptor.cloneProps call).

The former seems to be triggered by a JS call to setNativeProps, but we're not making any such calls from our code, so it's most likely coming from a third party library. I'll see if I can make a repro with this in mind.

Jul 07 '25 16:07 OrfeasZ

After some further investigation, the call to setNativeProps seems to come from react-native itself, and more specifically node_modules/react-native/src/private/animated/createAnimatedPropsHook.js. No luck creating a repro yet...

Both of them seem related to something trying to access a shadow node using shadowNodeFromValue while updateRuntimeShadowNodeReference is called from another thread, which in turn replaces the shadowNode pointer shadowNodeFromValue reads. I'm guessing this shouldn't be an issue, since shadowNode is a shared pointer, so any reference counting should be done atomically, which should mitigate the risk of trying to read it while it's being destroyed.

For now, due to lack of a better options, we've applied the following patch to react-native, hoping it improves the situation. We'll monitor and I'll post an update here. Keep in mind this patch is for RN 0.79.2, so it might not directly apply to newer versions.

react-native+0.79.2.patch

Jul 09 '25 15:07 OrfeasZ

@OrfeasZ I have the same issue on 0.79.5. Can this patch apply on 0.79.5 as well? Thanks

Jul 14 '25 16:07 kenyipp

We haven't seen any additional crashes since this patch was deployed, so it seems to be working. Not sure what next steps for this would be? Try to upstream on the react-native side?

@OrfeasZ I have the same issue on 0.79.5. Can this patch apply on 0.79.5 as well? Thanks

You can try but ymmv.

Jul 16 '25 17:07 OrfeasZ

After over a month in production with this patch, I can now confirm that this crash no longer occurs. However, the react-native team has not even looked at the PR. Maybe someone from the software mansion can raise it to them? Especially now with react-native switching to pre-built binaries for iOS, this will be more relevant to get into upstream sooner than later.

@OrfeasZ i'll try and give a feedback :D thank you for your effort

Hey @OrfeasZ 👋 Thanks for your commitment! We'll try to ping the right folks from Meta and see if it's possible to move this forward.

I have been monitoring it for a while, and I'm also seeing this happening in the latest version of React Native and Reanimated

@hatn-lumin you should try to patch following the patch of @OrfeasZ manually in your RN 0.80.0

Sep 15 '25 04:09 huanleanh

I was just running TSAN in my build and I also see this behavior. Will try the patch

Sep 16 '25 01:09 chrisnojima

Patch worked for me. Thanks @OrfeasZ

Sep 16 '25 14:09 umairgillani94

No action from meta. Issue is still present.

"react-native": "0.81.5"

Oct 31 '25 21:10 sadikyalcin

Still happening for me too with reanimated v4 and RN 0.81.x. Terrible.
