OK, have overcome another layer of the problem.  The prep_segment loop in
tagged_probe() in osloader.c was never exiting; the exit condition was
incorrect.  It was testing for sh->flags & 0x04 (last segment flag), which
is not always present.  Additionally, it would have skipped the last
segment itself.  I have changed the code to check for sh->length == 0 and
sh->flags & 0x04 as exit conditions.  This gets me past that hurdle, but I
don't know if it is a correct solution.

On to the next bug...
