The following code snippet causes an ICE (3.4 branch only)
when compiled with "gcc -O2 -ffast-math" on i686-pc-linux-gnu

===============================
double atan (double);

void foo()
{
   double x, y;

   do
     {
       goto L2;
     L1:
       if (x) goto L1;
     L2:
       x += atan (y);
       goto L1;
     }
   while (1);
}
===============================

bug.c: In function `foo':
bug.c:17: internal compiler error: in subst_stack_regs_pat, at reg-stack.c:1445
Please submit a full bug report, [etc.]
