--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
catch_exc.cc FAILs (other than timeout) seem to be a Cilk+ bug, if it ever
worked, it seems to have worked by accident.
The problem is that __cilkrts_rethrow conditionally throws an exception, but is
marked TREE_NOTHROW, thus there are no EH edges out of it.

* cilk-common.c (cilk_init_builtins): Clear TREE_NOTHROW
