Bootstrap failure on irix6.5 possibly caused by new C++ parser?

["Kaveh R. Ghazi" <ghazi@caip.rutgers.edu>]

Mark,

I'm getting a new bootstrap failure on mips-sgi-irix6.5 today on the
trunk.  It occurs after the 3-stage when building libstdc++-v3:

The annoying part is that the failure goes away if I add --save-temps,
so I assume it's not possible to provide a .ii file that reproduces
the crash in a cross compiler. :-(  If you still think it would be
useful to provide it let me know.

Bootstrap previously succeeded on 12/26 for irix6.2, as shown here:
http://gcc.gnu.org/ml/gcc-testresults/2002-12/msg01174.html and for
irix6.5 a couple of days before that.  So I think it's possible or
perhaps even likely that this was caused by the new parser.
