Extended Description

LLC is crashing on this testcase. I tried putting it through bugpoint -run-llc, but it couldn't reduce it any.

Also fails CBE for me on Mac OS X.

[sunfishcode]

compile with -gvn to reproduce the failure

the rest of the program

I managed to get bugpoint to reduce this down to a -gvn miscompilation.
To reproduce, compile tooptimize.ll with -gvn and compile tonotoptimze.ll
and link them (with g++) and the result is an executable that hangs. Compiling
without -gvn on tooptimize.ll produces an executable that executes and
terminates after a few seconds.
