--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
With the above options it started with
r12-3221-g1313111fdec0d0de4228b5e839ca728b3e4b106e
If I add -fexceptions, it started with
r12-2307-gb15e301748f0e042379909e32b3ade439dd8f8f9
With additional -fdelete-dead-exceptions it started with
r6-701-gaa953e2fc52e2196d62b9669a69c9e82de43dc3c=
