Re: EXC_BAD_ACCESS from sgxTextureGetImageRowBytes

Yes. I have been getting it with Excel 2010 and now with Word. Both programs are on Microsoft Office for Mac 2011. I have the 15" Macbook Pro 2.3 GHz Core i7 from mid 2012.

 

I have been reporting the Error Messages to Microsoft.

 

I have seen no fix for it on the Net.

EXC_BAD_ACCESS from sgxTextureGetImageRowBytes

Anyone seen this error before? I can't tell if my iPad 4 is dying or not; other apps work fine, but my app (which is now a near clone of Apple's GLKit example for setting up an OpenGL ES 2.0 iOS app) has started, frequently, crashing.

 

My application was running fine yesterday, almost a hundred source files (nearly a finished iOS game). Then it starts crashing, and after reverting back to previous revisions, it still kept crashing, and now I've reverted all the way back to its origins (a copy&paste of Apple's source examples), and it crashes with just this:

 

Code:

- (void)glkView:(GLKView *)view drawInRect:(CGRect)rect

{

    glClearColor(0.0f, 0.0f, 0.0f, 0.0f);

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

}
