I believe that's because they've switched to vtable thunks. Grr.
The announcement of glibc-2 stated that there would be no interface
changes in the foreseen future. Now, here we go.
I don't know which way to go: shall we rebuild libc6, explicitly disabling
vtable thunks, or leave it as it is and recompile libg++ and some C++
programs? The second way achieves better future compatibility (glibc,
libg++ and egcs folks consider the "old" virtual tables structure completely
obsolete, so it will soon be unsupported), but the mess it creates is
As for egcs, it is _by_default_ configured to compile using vtable
thunks. libg++-2.8.0 produces nasty warnings if it sees gcc compile
Life's getting harder without them, but more messy with them.

I would love to see your menu package on my Alpha. The problem is that
it is the only package so far that uses libg++ specific things like
Strings and stuff together with exceptions: exceptions are not
supported by the normal gcc on Alpha, while libg++ is not supported by
egcs. In other words, menu is too ++-ish :-(. I heard that nobody is
working on libg++ itself (not libstdc++, of course), so it is gradually
becoming unsupported and obsolete...
