With gcc 4.0.1, compiling the following results in an ICE:
void
foo ()
{
label: asm ("" : : "g" (*&&label));
}
Admittedly I don't expect it to do anything useful, but I was told in #gcc that
I should report the ICE anyways. (For what it's worth, this same code snippet
compiles without error in gcc 3.3 and 3.4.)
