bugpoint generated testcase

I'm getting a crash on the attached bitcode file for i686-apple-darwin:

[ssen at virgon]$ /Volumes/HD/ltmp/ssen/llvm/build/Debug/bin/opt
bugpoint-reduced-simplified.bc -indvars
WARNING: You're attempting to print out a bitcode file.
This is inadvisable as it may cause display problems. If
you REALLY want to taste LLVM bitcode first-hand, you
can force output with the `-f' option.

GEP!"), function visitAddRecExpr, file
