This was a long time ago, so I don't remember the particulars, but it was in a large Fortran-based CFD flow solver code. The code used a lot of dynamically-allocated arrays, and somewhere in there we had a bug that would occasionally manifest itself in a crash. The problem of course was that we couldn't consistently reproduce it. This was before the days of really good memory debuggers, or at least, before we discovered such tools, so the bug just kind of lingered on for a long time. The day I finally tracked it down was a red-letter day, for me personally anyways.
