Created attachment 82148 [details] valgrind output https://dl.dropboxusercontent.com/s/ynibt38hhdlyu1r/DungeonDefenders-x86.trace.bz2 Maybe you'll have better luck with this trace of dungeon defenders. I've never gotten it to play back right. It will crash with or without sb, LIBGL_ALWAYS_SOFTWARE and both 32 & 64-bit. The 32-bit drivers in my chroot are git but my 64-bit drivers are stable versions meaning mesa-9.1.3, libdrm-2.4.44, xf86-video-ati-7.1.0 and xorg-server-1.13.4. Most of the time it will segfault in a call to glDrawRangeElements but sometimes it will spam "The kernel rejected CS" before segfaulting. I attached a valgrind output. Running valgrind on the 32-bit binaries was impossible because valgrind doesn't support AVX instructions in 32-bit code so the output is from the 64-bit version. The stuff in my 32-bit chroot was not involved in any way so the problem is probably unrelated to that. I use gcc-4.6.3 and compile with these flags "-O2 -march=native -pipe"
