Check your logic.  It could be (for example) a variable that is
uninitialized only under rather rare circumstances, and even then still
works most of the time since the "uninitialized" value is usually
something non-fatal (see my BIGNUM patch earlier on the list today for
what may be an example of this).  

Rare or not rare doesn't have anything to do with data dependence, so
there's no harm trying to isolate causes.

Good idea.  You may also want to try it on a different machine, etc.

I don't know, but the CVS is web accessible.

I'm about to leave for a camping trip, but I'll catch up on the list 
Sunday evening.  If it's still a problem I'll try to replicate it.
