--- Comment #1 from Ahmed Asadi <ahmedasad...@gmail.com> ---
fun<false> gets instantiated to the following function:
int fun(int i)
{
switch (i)
{
case 1:
if (false)
return 3;
case 2:
return 4;
default:
return 5;
}
}
case 1 falls through to case 2, hence the warning.
When you insert [[clang::fallthrough]], it isn't reachable in fun<true> because
it will always hit 'return 3'.
Clang produces valid warnings in both cases. I'm marking the bug as invalid.
