Uh, don't I wish.  Any C or C++ program that tries to dereference a
null pointer, overwrite the end of a buffer, or free memory that has
already been freed can easily cause a signal 11.  And they aren't
always easy to track down either.

But yeah.  Hardware is usually the problem if you're talking about
different processes going SEGV without any discernable pattern.
