Random Crash At Launch - cocos2d::RenderState::StateBlock::setBlend(bool)

[ermanhaskan]

Hello

We are getting this very rare crash at launch across many android devices and all android versions. This error has been occurring in all cocos2d-x versions v3.x including the latest one. We tried everything to solve the crash but failed. We can cause the crash by rapidly closing and launching the app, crash occurs randomly.

signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 00000010 #00 pc 00ae0c2c ***/lib/libcocos2dcpp.so (cocos2d::RenderState::StateBlock::setBlend(bool)) #01 pc 00aee5dc ***/lib/libcocos2dcpp.so #02 pc 00a9e6d0 ***/lib/libcocos2dcpp.so (cocos2d::Director::setGLDefaultValues()+24) #03 pc 00a9f824 **/lib/libcocos2dcpp.so (cocos2d::Director::setOpenGLView(cocos2d::GLView)+112) #04 pc 009ef22b ***/lib/libcocos2dcpp.so (Java_org_cocos2dx_lib_Cocos2dxRenderer_nativeInit+230)

#00 -> /renderer/CCRenderState.cpp:732 -> _blendEnabled = enabled; #01 -> /renderer/ccGLStateCache.cpp:120 -> RenderState::StateBlock::_defaultState->setBlend(true); #02 -> /base/CCDirector.cpp:682 #04 -> /base/CCDirector.cpp:404

Version: cocos2d-x-3.12

The crash is caused by RenderState::StateBlock::_defaultState being nullptr. Other crashes happen if a control for nullptr is added for the crash line.

Do you have any ideas about this problem?

Thanks

[minggo]

@ermanhaskan could you please also paste the java log info? And what's the API level you build with?

[minggo]

@ermanhaskan will you please change AndroidMenifest.xml to

android:configChanges="orientation", "screenSize">

to have a try? More information about android:configChanges can be found here.

[dumganhar]

@ermanhaskan , try this:

android:configChanges="orientation|screenSize"

[minggo]

yep, @dumganhar 's version is right

[ermanhaskan]

I was using

android:configChanges="orientation|screenLayout|smallestScreenSize|screenSize|keyboardHidden"

Somehow I can't cause the crash even using old configChanges in my devices right now. I will use your version of configChanges in the last update and post the result here. Thanks.

[ermanhaskan]

Unfortunately we are still experiencing the crash using: android:configChanges="orientation|screenSize"

[ermanhaskan]

Just received this error on cocos2dx 3.13

[dhuang11]

We're also seeing the exact same crash in CC2DX 3.11, 3.13 and 3.13.1

[minggo]

@dhuang11 do you have a test case to reproduce it easily? And what's your environments:

• devices to test on
• NDK version
• what API version did you build with

more detail information is better.

[dhuang11]

We are seeing this crash on a number of Android devices. There doesn't appear to be a clear pattern.

We build using NDKr10e and with API version 23.

In house, we are able to reproduce this fairly easily on an Amazon Kindle Fire HDX. If we launch the app and close it a few times.

[minggo]

@dhuang11 did it also crash at cocos2d::RenderState::StateBlock::setBlend()?

[dhuang11]

Yes exact same stack trace - cocos2d::RenderState::StateBlock::setBlend() crash with the same call stack prior to that crash

[dhuang11]

Our game is linked to Crashlytics - here is a shared link to this crash: http://crashes.to/s/5d886e5ff64

It is our #1 crash according to Crashlytics and it is happening a larger proportion on Amazon kindle devices

[minggo]

Will you please use stand NDK toolchain to have a try?

@dhuang11 @ermanhaskan hi there, did you solve this bug?? it look like i'm encoutering the same bug as you two

[ermanhaskan]

@nbtthief I found no solutions to this problem :/

[hgwzyyx]

also happen in 3.9

[Guy-kun]

Has anyone had any more progress on this or has anyone found a cause? This issue is affecting an in-production app quite badly (1000 crashes+ per day) but no developer can reproduce it. The stack trace is the same as reported above

There seems to be no pattern to devices affected either except that they typically are in a low free-Ram state

I'll keep trying to hunt down a reproducible device but on a Google Pixel aggressively restarting/foregrounding the app does not cause any similar issues.

[Guy-kun]

Still looking for any further information on this or if anyone found a cause... Still #1 crash bug for an app in production together with variants of this and setBlend()

[umair6]

I am also facing this issue in my game.

[Obg1]

Any fix for this? Getting this on 3.16

[bolso80]

@ermanhaskan @Guy-kun @hgwzyyx were you able to fix this problem?

Thanks
