--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The division and modulo functions in glibc are built with -fexceptions (since
r190483 it seems), so I guess you don't really want to build them with -O0,
because in that case you might end up with some _Unwind_Resume,
__gcc_personality_v0 etc. not optimized away like it happened to you.
You'd need to link with -lgcc_eh to get those, as it is not in -lgcc
(intentionally) or -shared-libgcc.
