Will there be a follow up patch to fix the crash scenario? Is there

Triggering this bug is a bit esoteric but the impact is pretty nasty

The patch origin is unknown. I got it from Tomas and Bud who think it may
have originated from HP. I cleaned it up, compile tested it, and sent it
on. I'll review my procedures for future patches.
