This simple testcase appears to trigger the same ICE :
$ cat ice.c
void f(void)
{
0 || 0 / 0 ? : 0;
}
$ gcc -w ice.c
ice.c: In function ‘f’:
ice.c:3:12: internal compiler error: in gimplify_expr, at gimplify.c:7790
0 || 0 / 0 ? : 0;
^
Please submit a full bug report,

The new test case in #c10 ICEs gcc 4.8-20120722, 4.7-20120721, 4.6-20120720,
and 4.5-20120628, but not gcc-4.4.7, for me on x86_64-linux.

If something ICEs on current trunk it's clearly a different bug from this
one, which is fixed, and so would need to be filed as a separate bug.
