Well, I've been learning some unpleasant truths :-(. Hope to have
some fixes to commit in the next few days.
The immediate cause of one coredump I saw was that someone who was
overenthusiastically replacing sprintf's with snprintf's had written
snprintf(tempname, strlen(tempname), ...);
where tempname points to just-allocated, quite uninitialized
memory. Exercise for the student: how many different ways can
this go wrong? Unsettling question: how many other places did
that someone make the same mistake??
I don't have time for this right now, but it'd be a real good idea
to grep the source for strlen near snprintf to see if this same
problem appears anywhere else...
