--- Comment #10 from Martin Liška <marxin at gcc dot gnu.org> ---
Ok, so it's as old as ICF. There's a minimal test-case:

$ cat test.cc
#pragma GCC visibility push(default)
void foo1() { __builtin_printf ("foo\n"); }
#pragma GCC visibility pop
void foo2() { __builtin_printf ("foo\n"); }

int main() { foo2(); }

(for older revisions than r244273 one needs:

$ cat test.cc
void foo2() { __builtin_printf ("foo\n"); }

#pragma GCC visibility push(default)
void foo1() { __builtin_printf ("foo\n"); }
#pragma GCC visibility pop
int main() { foo2(); }
