--- Comment #20 from Richard Biener <rguenth at gcc dot gnu.org> ---
Testcase:

int __atoi  (const char *) __asm__("atoi");
extern inline __attribute__((always_inline,gnu_inline))
int atoi (const char *x)
{
  return __atoi (x);
}

int bar (int (*)(const char *));

int main()
{
  return bar (atoi);
}

----

int bar (int (*fn)(const char *))
{
  return fn ("0");
}
