Yeah, I just didn't know what form this list prefers in terms of info to be able to work on things, which is why I'd
preferto hire a regular participant of this list.  If gcc 'where' stack traces from core files are what you want, we
cando that.   

I suspect that the problems may be platform-or-build related, because we've often had trouble replicating customer
problemson our own sysems. For example, we had many reports of problems with 7.2.x, and saw it crash often on a
customer'sredhat machine that we had ssh access to, but couldn't make it crash in our own lab. :(  That's why we need
help. If we could make a simple C test case that crashed pgsql, I'm sure you guys could fix the problem in a jiffym but
localizingand recreating a problem is always 80% of it.
