The stack traces aren't nonsense--they're just innocuous, they show
that the interpreter was evaluating something about the way you'd
expect it to when the crash happened.  It will take more detailed
digging in the core dump, and better knowledge of the interpreter guts
than I currently have, to see what exactly is wrong.

Unfortunately, the crashes don't happen often enough for it to be
practical to run under gdb.
