There is a crash when doing glclearColor on the arm Mali-G71, Mali-G72

sgKim

Hello, I'm a developer in fiends of graphic.

I found the bugs my application regarding mali.so. So, I want to get some advices.

My app accor an abnormal termination when doing glClearColor().

It happens not always, but quite often.

There is the callstacks. (refer to below)

I wanna get the answer.

Thans for reading my post.

Best Regards.

    In that case, the timing of abnormal termination is before the rendering something.
    There is the source code. (refer to below)

     //render n-1 frame
     //then, do swapbuffer

     //prepare rendering n frame
     glEnable(GL_TEXTURE_2D);
     
     glEnable(GL_CULL_FACE);
     glEnable(GL_DEPTH_TEST);
     glDisable(GL_BLEND);
     glEnable(GL_FOG);

     glActiveTexture(GL_TEXTURE0);

     glClearDepthf(1.0);
     
     glFrontFace(GL_CW);
     
     glCullFace(GL_BACK);
     glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);

     glDepthFunc(GL_LEQUAL);
     glAlphaFunc( GL_GREATER, 0.0f );
     
     glLineWidth(1.0f);
     glPointSize(1.0f);
     
     glClearColor(245.0f/255.0f, 243.0f/255.0f, 222.0f/255.0f, 1.0f);
     
     glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); // here
