the bootstrap failed:

A backtrace for the libstdc++ fail in futures.cc is like this:

This makes me think that this could have been broken by the VTA.
Alex, could you please have a look at this?
Thanks,

------- Comment #3 from rguenth at gcc dot gnu dot org 2009-09-20 20:22 -------
it just means that graphite doesn't properly deal with DEBUG_STMTs and thus
different code is generated with/without -g.
