Here is a reduced testcase that shows the ICE with that patch:
template <typename A, typename B>
static bool
equal (A a, A b, B c)
{
for (; a != b; ++a, (void)++c)
if (!(*a == *c))
return false;
return true;
}
Seems there are many reasons why it can not set *loc_after_labels, if it parses
something into non-NULL statement, or various pragmas, or EOF.
