I worked on a testharness for (wait for it) petrol pumps some years ago,
little embeded controller spoke to its DOS (not exactly the easiest
environment to track crashing bugs under) master which logged its
piteous whinings. I inherited the dos part of it and worked mostly on
creating the other end of it. Near the end of the project we gave it
extensive long burnin tests, sadly overnight tests would always crash
out for some obscure reason.  Tracking it down showed that my
predecessor's "add new entries to the end of its linked list" function
recursively called itself with each following link until the terminating
one showed up. Of course it died miserably when it ran out of stack. I'm
sure he felt he'd done a good days work when he planted that bomb for
me.
