Crash in cocos2d::GLProgramState::updateUniformsAndAttributes()

ebouchard · January 13, 2022, 11:19am

On my newly launched game, I keep getting this crash from android crash logs. I cannot reproduce it myself. I have no clue how this is happening. Any pointers would be appreciated.

It crashes in this function at the beginning:
void GLProgramState::updateUniformsAndAttributes()

This is called by:

void TrianglesCommand::useMaterial() const
{
//Set texture
GL::bindTexture2D(_textureID);

if (_alphaTextureID > 0)
{ // ANDROID ETC1 ALPHA supports.
    GL::bindTexture2DN(1, _alphaTextureID);
}
//set blend mode
GL::blendFunc(_blendType.src, _blendType.dst);

_glProgramState->apply(_mv);

}

So at this point, I would assume _glProgramState is NULL or corrupted.

Here is the stacktrace:

I can ask engineering if they have thoughts on this.

ebouchard · January 14, 2022, 12:05am

Thanks. It would be helpful. Just an idea of the possible cause because the stack trace does not help at all figuring out what when wrong before that

It happen when call cocos2d::Renderer::drawBatchedTriangles, like built-in shader program, maybe the resource has destroy or no create success, if you can reproduce the problem, please attach the test project .
