I'm a noob at debugging, but I want to try to identify the cause of a segfault. The packaged dosbox is stripped, so I assume I'll have to rebuild it myself. After that, what tools do I need, and how do I go about creating a report that will be useful to the developers?

I'm hopeful that this will lead to something fixable, because although the segfault is not deliberately reproducible, when it does happen, it's always under the same circumstances: right when I win a battle in Master of Magic...
