Definitely. But if you've built with --enable-debug and not stripped
the resulting executable, we ought to get line numbers as well, plus
the arguments to each function on the stack. That would help a lot
more. The only things that get dereferenced in that function are
"scan" and "parallel_scan", so it's a good bet that one of those
pointers is pointing off into never-never land. I can't immediately
guess how that's happening, though.
