Obvious question, but have you got Hudson set up to point to the same Maven repository as your command line build?

In native code you can get a shot at walking the callstack by installing a [Vectored Exception handler][1].

The best quality control for gcc is the linux kernel. GCC is the compiler of choice for basically all major open source C/C++ programs. A released GCC, especially one like 4.3.X, which is in major linux distros, should be pretty good.

Functions are first class citizens in F#. You can therefore pass them around just like you want to.

EDIT: MethodBase is probably a better way to just get the method you're in (as opposed to the whole calling stack). I'd still be concerned about inlining however.

I suspect these are related to the SQL Server Agent trying to login to a database that no longer exists.
