[LLVMdev] Weird memory bug

This was indeed a memory issue - the hard datasize limit on my freebsd
box was 512 mb and this opt went over.  Increasing hard limit fixed
the problem.

However, most unices have a 512mb limit - maybe insanely huge
functions as this one should be automagically split somewhere?
