Actually, it is more likely overconfidence on their part -- thinking
they understand something when, in fact, they are largely clueless.
"Enlightenment" possibly coming when they find they've shot
themselves in the foot.

[If something "unexpected" happens to a hardware design, it is quickly
dismissed as "outside the recommended operating conditions".  Wouldn't
it be nice to claim that same excuse for "misbehaving" software?]

Software is repeatable (in the absence of hardware errors).
So, seeing "something" once means there is some condition that
caused it to manifest.  Your inability to reproduce THAT
CONDITION doesn't mean the problem has gone away -- you're
just being lazy and HOPING for the best.

Do you see standard library (et al.) functions accounting for
the fact that the address space "wraps"?  Most will gladly
do what they are told -- regardless of how nonsensical it
may be (what does it mean to clear the last 100 bytes of
memory starting at LAST_MEMORY_ADDRESS - 72?)  Or, trying to
print "(unsigned) -1" digits with leading zero suppression?  Or, ...

How much stack does your piece of code (AND EVERYTHING ON WHICH IT
RELIES) *require*?  Do you even know how to go about getting a
DEFINITIVE answer?  What (specifically) will happen if you exceed
that value?
