backtrace without debug symbols

HD 7970M, mesa recent git, llvm 3.5 recent svn.


Antichamber based on Unreal Engine is available in the latest Humble Bundle.


The crash doesn't seem to happen deterministically, I produced such a crash two
times now by playing the game for a few minutes and then it randomly crashed.

UDKGame-Linux:
/build/lib32-llvm-svn/src/llvm/include/llvm/CodeGen/SlotIndexes.h:417:
llvm::SlotIndex llvm::SlotIndexes::getInstructionIndex(const
llvm::MachineInstr*) const: Assertion `itr != mi2iMap.end() && "Instruction not
found in maps."' failed.

Program received signal SIGABRT, Aborted.
0xf7fdb430 in __kernel_vsyscall ()


The backtrace I attached is without debug symbols so maybe isn't too
informative. Later I will compile with debug symbols and provide a better one
if needed.
