Here's a smaller testcase:

===============================
double c, d, e;

void foo()
{
    if (e-1) d=0; else d=0;
    c=d;
    if (e) d=0;
}
===============================

It crashes GCC 3.3.x when compiled with
"-O -frerun-cse-after-loop -ffast-math -march=pentium4 -mfpmath=sse"

The testcase crashes GCC 3.2.x, but not GCC 3.1 when compiled with
"-O3 -march=pentium4 -mfpmath=sse"
