John, the pretty-printer for go is covered by bug 1283626, and it sounds like 2to3 is able to convert that file automatically. Hope that helps.
Adding gcc-4.8 to this bug since that's where the STL pretty-printer comes from, and I think it's more likely to be fixed there than by reverting gdb back to linking against python2. ** Also affects: gcc-4.8 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1258642 Title: gdb: Python 3 incompatible with libstdc++ pretty printers.
