Created attachment 44240
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=44240&action=edit
common.i.xz

I suspect that when adding a new bug, if the attachment exceeds the file size
limit, it is silently ignored. (or the error message was small enough that I
didn't see it)

anyways, here it is.

Reduced test-case:

$ cat pr86064.i
int a;
__attribute__((__cold__)) void b();

void e(int *);
int f();

void c() {
  int d;
  e(&d);
  a = d;
  if (f())
b();
}
