Summary: Segmentation fault compiling C source with no
optimization on x86/32-bit under 4.4.3

I'm working on a memory allocator and trying to track down a bug somewhere
using gdb, so I needed to build on a 32-bit x86 system without optimization as
all the important values were being optimized out.
System:
AMD Phenom(tm) II X4 940
Ubuntu 10.04.1 (32-bit)
Linux luka 2.6.32-25-generic #45-Ubuntu SMP Sat Oct 16 19:48:22 UTC 2010 i686
GNU/Linux
