... the test program included in the bug reports still
generates incorrect output on a RH 6.0 system:

$ uname -a

$ g++ -v

Comment 1 Jim Kingdon 1999-07-26 21:04:59 UTC

If I understand the discussion of bug #1075 correctly, the problem
cannot be solved without changing the C++ ABI (one way or the other,
either to -fno-vtable-thunks, or for the "ABI overhaul" which Jason
referred to on egcs-bugs).  The current plan (and subject to all the
usual disclaimers about we don't preannounce releases or however those
disclaimers go) is that we are not going to change the C++ ABI in
the next release of Red Hat Linux (for example, we will ship
egcs 1.1.2 rather than gcc 2.95).
