[Bug c++/44298] New: code addressed only by label with it's address taken is ignored

[yuri at tsoft dot com]

The testcase below passes the entry point to 'lll' call as an address of the
label ll_def. printf line disappears completely.

Obviously people should only use such code when they really know what they are
doing. But compilation result here is complately wrong and isn't usable in any
way.

--- testcase ---
#include <stdio.h>
#include <stdlib.h>

__attribute__ ((noinline)) void lll(void*) {
}

void mainx() {
  lll(&&ll_def);
  return;
ll_def:
  printf("default\n");
  return;
}
