Test case

I have no idea which category should be used to file this bug, so here it goes:

cc -O2 -pipe   test.c  -o test
Stack dump:
0.      Program arguments: /usr/bin/clang-cc -S -disable-free
--relocation-model static --disable-fp-elim --unwind-tables=1 --fmath-errno=1
-O2 -arch x86_64 -o /tmp/cc-AmsTYM.s -x c test.c 
1.      <eof> parser at end of file
2.      Per-module optimization passes
3.      Running pass 'CallGraph Pass Manager' on module 'test.c'.
4.      Running pass 'Loop Pass Manager' on function '@zlascl_'
5.      Running pass 'Loop Invariant Code Motion' on basic block '%L10'

I couldn't reduce the test case any further... It seems the crash goes away if
I remove random pieces of code.
