I get SIGSEGV when my C and C++ programs exits. I have tracked it down to the
__do_global_dtors_aux function. The newly added code under HIDDEN_DTOR_LIST_END
does not check if the function ptr from the list is 0 - which the old code
below does. On my platform (no-mmu ARM, uclibc, uclinux) at least there are
zero-pointers in that __DTOR_LIST__.
This patch solved the issue for me:

------- Comment #1 from ramana at gcc dot gnu dot org 2009-04-29 14:38 -------
The new code has a value of max_idx of DTOR_END - DTOR_LIST - 1. You might want
to see why your implementation has a value of max_idx > 1. It doesn't appear to
be a target bug yet - Please check this and get back with any more information
with a compiler of more recent vintage.
