But lets assume that a good programmer is writing software and
it comes to his attention that there is a buffer overflow, or
that user input is not being filtered, or that user input is being
passed to a printf type function.  What happens next?  Well, it
depends on how many bugs there are, how much other work needs
to be done, and very importantly, what the perceived impact of
that bug is.  You cannot imagine how many times a bug is pointed
out and the author of the software says "ok, that bug can only
happen if the user does something stupid, and it is not exploitable.
Lets defer that one."

This suggests that it's reasonable for a program to segfault because the
user made a mistake, instead of having some non-fatal form of error
handling.  I don't think that should be acceptable at all, though I agree
it's very common.  If I had a dollar for every time I've lost work because a
segfault or GPF happened before I saved my document...

A "defer" means "we'll fix it, but we have more important things to
do first."   I wouldn't say its an acceptance that its "reasonable"
behavior.
