Created attachment 29242 [details] Test program I've here a bigger program which worked in previous (cannot tell which) version of this package, but currently it seems to crash when it calls glReadPixels. I tried to create a similar testcase for the bug report and noticed that it only(?) happened when I tried to read from frontbuffer. The simple test is attached to this mail. It can be compiled with: g++ -o readpixels_z readpixels_z.cpp `sdl-config --cflags` `sdl-config --libs` -lGL -lGLU Backtrace: #0 0x00000000 in ??
