agreed it's an unwinder bug, I suppose we need a non-Java reproducer. As of
Darwin11, nothing should be using the libgcc_s unwinder (and really it
shouldn't be used for darwin10).  The broken unwinder in the darwin9 libgcc_s
can't be easily fixed (44107) - and the resolution there is to update the
installed lib.

It's possible that we're going to struggle to get a fix unless/until we can
make output compatible with the compact unwinder.

We can leave this open, but as stated,  someone should try to find a non-Java
reproducer.
