find . -type f | xargs grep do_global_ctors_aux
on a linux machine in the gcc source tree will show you all uses of
do_global_ctors_aux, there are only about a hundred of them, and most
of them are obviously not relevant.  You can ignore the ia64, pa, and
ChangeLog file hits.  That gives a couple dozen, of which the most
interesting one is this one
./libgcc/crtstuff.c:CRT_CALL_STATIC_FUNCTION
(__LIBGCC_INIT_SECTION_ASM_OP__, __do_global_ctors_aux)
