           Summary: Out-of-memory on Scalar Evolution on long loop'd
                    expressions
           Product: libraries
           Version: trunk

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'
3.      Running pass 'Induction Variable Simplification' on basic block
'%for.body'
Segmentation fault

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