Another testcase that started ICEing with r235842.
int a, b;
int
fn1 (int p1)
{
return p1 < 0 ? p1 : a;
}
void
fn2 ()
{
lbl_100:
b = 1;
for (; b != 21; b = fn1 (b))
;
goto lbl_100;
}
with -Ofast with a different backtrace:
ice.c:9:1: internal compiler error: in combine_blocks, at tree-if-conv.c:2219
