The following invalid code snippet causes an ICE since GCC 4.0.1:

===============
int x[1/0];
===============

bug.c:1: warning: division by zero
bug.c:1: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

Before we got:

bug.c:1: warning: division by zero
bug.c:1: error: storage size of 'x' isn't constant
