[Mesa3d-dev] bug w/OSMesa16 glCopyPixels

[Eric P. <eri...@di...>]

It seems that OSMesa16 does not like glCopyPixels. I've tried this on regular 
Mesa and it does not pose a problem. If your buffer is of size WIDTHxHEIGHT, 
doing:
glCopyPixels( 0, 0, WIDTH, HEIGHT, GL_COLOR );
will segfault. In fact, in my tests WIDTH and HEIGHT were 128, and passing a 
value as low as 10 for the width and height of the copy would result in a 
sefgault.

Any clues as to what is going wrong?

I'm attaching an example program & Makefile which reproduces this.

PS: Setting the raster position beforehand does not help.

Thanks for having a look,
