- Subject: GCC 4.0.1 Status (2005-06-13)
Those who have been watching carefully will note that there is no sign
of an actual 4.0.1 release.
There are two blocking issues at the moment:
1. Benjamin Kosnik reports that there are ABI and/or version-symbol
problems between 3.4.x and 4.0.x version of libstdc++, and is trying to
sort out a solution.
2. Jakub Jelinek reports that we're miscompiling GLIBC.
The latter problem seems to me to be as severe as the KDE bug that was
the impetus for this release. The libstdc++ problem also seems serious.
In particular, Benjamin reports a mangling change that sounds like
something that should perhaps have been controlled by -fabi-version, but
I have not received a test case for that problem.
(I should confess that I am so skeptical about the likelihood that we
have maintained full libstdc++ compatibility anyhow that I am not
entirely convinced that we are not just seeing one of several problems...)
We're in a holding pattern (branch frozen) until we resolve these issues.
