--- Comment #14 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
Here's a simple testcase for this issue (triggers for 4.8.3 and 4.9.1):
markus@x4 linux % cat exit.i
int a, b, c;
void fn1 ()
{
int d;
if (fn2 () && !0)
{
b = (
{
int e;
fn3 ();
switch (0)
default:
asm volatile("" : "=a"(e) : "0"(a), ""(0));
e;
});
d = b;
}
c = d;
}
markus@x4 linux % gcc -fcompare-debug -O2 -c exit.i
gcc: error: exit.i: -fcompare-debug failure (length)
markus@x4 linux % gcc -fcompare-debug -Os -c exit.i
gcc: error: exit.i: -fcompare-debug failure (length)
