--- Comment #3 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
Still a problem even today.
The 'optimized' gimple code is:
__attribute__((noinline))
void foo (struct Foo f)
{
int * _1;
<bb 2> [local count: 1073741824]:
_1 = f.p;
*_1 = 0;
return;
}
which then gets expanded to copy the incoming argument to the stack
