Intermediate source
The following intermediate crashes in Scalar Evolution when run through "opt"
(rev 188181):
Stack dump:
0. Program arguments: ~/builds/llvm/bin/opt M.ll -O3 -S
1. Running pass 'CallGraph Pass Manager' on module 'M.ll'.
2. Running pass 'Loop Pass Manager' on function '@repeated_expression'

Running a 32 bit linux, the opt process rises in memory usage before suddenly
crashing.
