GDB crashes with: ImportError: No module named libstdcxx.v6.printers
This is a bug in /usr/lib/debug/usr/lib/$triple/libstdc++.so.6.0.18-gdb.py; if it were operating correctly, you would only see the ImportError once, and the pretty-printers would work.
See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=701935#18 for some information about what's going wrong here. This worked okay in Debian's gcc-4.7, but until recently did not work in gcc-4.8 on Debian. I'm not sure if I even tried this with gcc-4.6.
Regardless, you can patch that file to look in the right place.
