It happens on IOS too, the same error.

PR_TAGGED_ADDR_ENABLE

A workaround as an app developer: Ask Android to relax on crashing out on address sanity (this won't prevent your app from crashing if you're not careful, though some apps genuinely have a need to manipulate the higher-bits of pointers, which when it goes wrong will end up but in a different crash). This is what we do for our app (code):

https://github.com/celzero/rethink-app/issues/962

+   <application android:gwpAsanMode="never"
        android:name=".RethinkDnsApplication"
        android:largeHeap="true"
+       android:allowNativeHeapPointerTagging="false"
+       android:memtagMode="off"

It did not work :(

[hubertwang]

I got the same issue. @g1henx have you figured out how to solve it?

[g1henx]

Hey, i did not.

[andrewg4]

Any suggestions on it? Same crash on Pixel 2 and Pixel 3a devices
