I think that would be me.  :-)  In the process of writing a patch to
implement this, I ran across what looked like another out-of-bounds,
uninitialized string/memory error type of SIGSEGV.  I've got it tracked
down pretty well, but it's hard to explain.  Also, about 2 days after
I had it tracked down (and sent a rather sketchy description of it to
Tobi O.), I got rather busy with work, and have not gotten back to it

If someone wishes to finish the job, I think I should be able to dig
up the patches I have, etc...
