glClear(mask) is sometimes crashing

[IrrlichtForiOS]

The following Code in COGLESDriver.cpp is crashing sometimes randomly.

Code: Select all

//! clears the zbuffer
bool COGLES1Driver::beginScene(bool backBuffer, bool zBuffer, SColor color,
        const SExposedVideoData& videoData,
        core::rect<s32>* sourceRect)
{
    CNullDriver::beginScene(backBuffer, zBuffer, color);
 
#if defined(_IRR_COMPILE_WITH_IPHONE_DEVICE_)
    Device->displayBegin();
    glBindFramebufferOES(GL_FRAMEBUFFER_OES, ViewFramebuffer);
#endif
 
    GLbitfield mask = 0;
 
    if (backBuffer)
    {
        glColorMask(GL_TRUE, GL_TRUE, GL_TRUE, GL_TRUE);
        Material.ColorMask = ECP_ALL;
 
        const f32 inv = 1.0f / 255.0f;
        glClearColor(color.getRed() * inv, color.getGreen() * inv,
                color.getBlue() * inv, color.getAlpha() * inv);
 
        mask |= GL_COLOR_BUFFER_BIT;
    }
 
    if (zBuffer)
    {
        glDepthMask(GL_TRUE);
        Material.ZWriteEnable = true;
 
        mask |= GL_DEPTH_BUFFER_BIT;
    }
 
    glClear(mask); // EXC_BAD_ACCESS
    return true;
}

Does someone know, how to solve this issue?

The problem is unlikely to be in this code. Trying putting a printfs before and after the glClear: printf("calling glClear\n"); fflush(stdout); glClear(mask); printf("glClear called\n"); fflush(stdout);

What will this do to solve the problem?

If this is a new problem (since last week) it might be because of the recent merge from trunk. Nadro is working on this and the priority was on ES2. If it's been a while longer then we need an example to reproduce the crash.

Hi,

Thanks for a report, I'll try to check that during fixing ES1 driver in ogl-es branch (probably near next week).
