I didn't realize the above crash was with your binaries.  If it was,
it's probably a different problem.  Leo, if you have a way of
reproducing this, please run under GDB and produce a backtrace, or
better yet, show the recipe (and file a bug report).

Specifying --no-opt is enough.

With --no-opt, -fno-omit-frame-pointer should have no effect, because
this optimization is turned on by -O1.
