This weekend I upgraded, and libstdc++6 went from 4.5.2-4 -> 4.6.0-2.
(1) how do I determine what version of libstdc++6 that the previous debian version of that package was using? That, is, the current package provides the file /usr/lib/libstdc++.so.6.0.15 and a link /usr/lib/libstdc++.so.6 -> libstdc++.so.6.0.15. I assume the previous debian version did the same, but with some other file, maybe libstdc++.so.6.0.14? How do I find out what that file was?
I went to snapshot.debian.org, searched for the binary package libstd++6, and grabbed the .deb file for version 4.5.2-4 on amd64. I opened that deb-file (with the decompression program in gnome) and it contained /usr/lib/libstdc++.so.6 and /usr/lib/libstdc++.so.6.0.14, as you expected.
(2) How do I locate and install the previous version from a debian repository?
Download the .deb from snapshots.debian.org and install. The normal warnings and disclaimers when downgrading library packages all apply.
