Nice. More widely useful might be a docker image or some other portable app container offering these packages.

Updating gcc in this case may or may not fix the crash. I fixed it by downgrading gcc, but even that result can't be taken to imply a compiler "bug", just a change in behaviour in gcc-4.6.3 which may even benefit someone somewhere. Updating needlessly makes fault-finding more difficult, as witnessed by the effort required to isolate the "kernel BUG" regression earlier in this thread. Dependable tools are more important to me than new tools.
