 Apparently, GNATS does not handle attached files correctly (or maybe I
 have to name them differently), anyways.  Here're direct links for both
 latest patch by Jeremie and RELENG_6 backport:

 Hans Petter Selasky <hselasky(at)c2i.net> raised a point about this part
 of the patch:
 
 >  +      if (restart)
 >  +              p = (uByte *)(restart) + restart->bLength;
 
 that maybe we "can add some extra range checks here.  Remember the
 descriptors come from the device itself, and might be corrupt."
