Original C file triggering the crash

The attached C code triggers an assert when compiled with clang -O2 (no issues
with clang -O1).

The code itself is generated by csmith, so it's quite convoluted. I used a
combination of bugpoint and manual modification to slim down the input bytecode
to something more reasonable, hope it helps.
