The attached bitecode file causes opt to crash at -O2.

0.      Running pass 'CallGraph Pass Manager' on module 'code.bc'.
segmentation fault

If I run my jit with assert-enabled LLVM it outputs (I have no access to an
assert-enabled opt):

Assertion failed: Begin + idx < End, file
D:\dev\llvm\head\include/llvm/ADT/SmallVector.h, line 129
