Hardware: Radeon 7870 (Pitcairn) I'm using the Oibaf repository (https://launchpad.net/~oibaf/+archive/graphics-drivers/) on xubuntu 14.04 I also have installed the "xserver-xorg-video-radeon-dbg" debug package from there. In the 3d game Tesseract (http://tesseract.gg/) some shader (sky shader?) causes llvm to run out of registers or Segmentation fault. And MSAA over 2x will cause LLVM to terminate because of "our of register" errors. Fast and dirty "How to build tesseract debug version": You need the SDL2/image/mixer packages. Command out the first two lines in the tesseract src/Makefile and add one line for debug options like this: #CXXFLAGS= -03 -fomit-frame-pointer -ffast-math #override CXXFLAGS+= -Wall -fsigned-char -fno-exceptions -fno-rtti CXXFLAGS= -g3 NOTE: "make install" only moves the binarys into the folders ../bin_unix/ cd src make make install cd .. gdb bin_unix/native_client Then trying to load the first map: MAP BROWSER -> complex And this will happen: Program received signal SIGSEGV, Segmentation fault. 0x00007fffeb529c64 in llvm::TargetInstrInfo::foldMemoryOperand(llvm::MachineBasicBlock::bundle_iterator<llvm::MachineInstr, llvm::ilist_iterator<llvm::MachineInstr> >, llvm::SmallVectorImpl<unsigned int> const&, int) const () from /usr/lib/x86_64-linux-gnu/libLLVM-3.4.so.1 (gdb) bt #0 0x00007fffeb529c64 in llvm::TargetInstrInfo::foldMemoryOperand(llvm::MachineBasicBlock::bundle_iterator<llvm::MachineInstr, llvm::ilist_iterator<llvm::MachineInstr> >, llvm::SmallVectorImpl<unsigned int> const&, int) const () from /usr/lib/x86_64-linux-gnu/libLLVM-3.4.so.1 #1 0x00007fffeb3eb039 in ??
