--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Indeed:
_Atomic float x = 5;
void
bar (float y[(int) (x += 2)])
{
}
is accepted while
_Atomic float x = 5;
void
foo (void)
{
void bar (float y[(int) (x += 2)]) {}
}
ICEs. The problem is that create_artificial_label called from
build_atomic_assign from the nested function parameter declaration parsing sets
LABEL_DECL to current_function_decl
