This would probably work, but I think it's less useful.

This won't work.  You're right; it's unparseable.  Could you manage to
generate "bar::foo:F(0,1)" instead?  GDB should handle that correctly
as-is.

i386-linux can do this.  I'd offer to do it, but only if Michael's too
busy - his test setup is vastly more thorough than I could manage.
