[llvm-dev] LLVM error while executing Python on KLEE

[Dipanjan Das via llvm-dev]

Hi Everybody,

I compiled Python with llvm-gcc to generate LLVM bitcode to be run on top
of KLEE. Though python.bc gets generated successfully, KLEE throws a bunch
of warnings during execution. Moreover, there's an LLVM error at the end
that causes KLEE to abort: "LVM ERROR: invalid argument to evalConstant()".
Does anybody have any clue on this?
