[Bug bootstrap/41401] New: Graphite branch broken after merge

[spop at gcc dot gnu dot org]

After the merge from trunk into the Graphite branch:
svn://gcc.gnu.org/svn/gcc/branches/graphite@151820
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,

The patch svn://gcc.gnu.org/svn/gcc/trunk@151362 breaks bootstrap with graphite
enabled.

2009-09-03  Alexandre Oliva  <aoliva@redhat.com>

        * toplev.c (process_options): Enable var-tracking-assignments
        by default if var-tracking is enabled.

------- 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.
