I believe it's invoked for functions that call setjmp. 70K seems high for that though.

There used to be a bug that caused it to be invoked for functions that called setjmp, but the bug was fixed.


It is invoked for this test case:


void foo (void *) __attribute__ ((noreturn));

void
bar (void *x)
{
  if (__builtin_setjmp (x))
    return;
  foo (x);
}
