llvm dev - Oct 2012 - [LLVMdev] seg fault in AddReachableCodeToWorklist

Hi,

I am running into this segmentation fault while running a simple function
pass on some C benchmarks

Program received signal SIGSEGV, Segmentation fault.
0x00000000005c5c00 in AddReachableCodeToWorklist(llvm::BasicBlock*,
llvm::SmallPtrSet<llvm::BasicBlock*, 64u>&, llvm::InstCombiner&,
llvm::TargetData const*) ()


What can be the possible reasons of the segmentation fault here? I am
trying to figure it out for many days now. I would appreciate any help.

Thanks,
Naznin

Hi Naznin, do you build LLVM with assertions enabled?  Does your IR pass the
verifier?

Best wishes, Duncan.
