libstdc++6 is currently configured to use the mt allocator based on discussions in April 2004 with upstream libstdc++ developers. This configuration turned out to be a mistake (memory leaks and the allocator is still buggy), other distributions did change back to the new allocator (the default one) in mid-2005 (FC in July 2005). The change does not have an effect on symbols exported from libstdc++, but it does have an effect on symbols exported by libraries which use containers (using an allocator) from the template headers.
The proposal by upstream is to configure libstdc++ to use the new allocator again (the default one). The change will break some libraries, as seen in #336114, which can be fixed by rebuilding these libraries against a reconfigured libstdc++. * Identify all library packages depending on libstdc++ and exporting *mt_alloc* symbols. * Rebuild these libraries and depending packages. Note that partial upgrades won't work with this procedure. To make this work, we would have to change the package name for all libraries affected. -- Matthias -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
