The problem is in gdb's varobj.c: it is incapable of handling c++ right
now. I don't know why this is an issue all of a sudden. My only guess is
that gdb hadnles the v3 abi a little differently.

I am currently trying to get patches through gdb, but it is turning out to
be a major chore.

May I suggest you watch for updates to varobj.c in gdb's repository or
peeking for posts to gdb-patches AT sources DOT redhat DOT com which involve
varobj.c?

If you're really desparate, I could send you my patches, for a small
handling fee of $5,000. Ok, maybe just some testing. O:-) Email me
privately if you'd like to be a guinea pig for this.

Keith
