I don't think it's necessarily a problem with the programmer's code that
debugging can find.  It could be using so much memory in such a random
pattern that the machine goes into a swap storm or it could be stressing
the system in such a way as to cause a hardware problem (overheat, not
enough power, CPU errata like the AMD TLB bug in Phenom, etc).
