this is easier.

The testcase from PR77955:
markus@x4 /tmp % cat fall.c
void bar(int);
void foo(int i) {
switch (i) {
case 1: {
bar(1);
// fall-through
}
case 2:
bar(2);
default:
break;
}

Thanks for investigating.
I already pushed a workaround for gnulib's vasnprintf problem
(http://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=e63f5eb55570a1ea3e51ce47df33689785e085c1).

int
foo (int x)
{
switch (x)
