You don't say what machine this is on, and that's important, because the
definition of "bus error" is system-specific.  Typical cause is accessing
a multi-byte value at an improper alignment or accessing a part of your
address space which has not been allocated.  The usual reason is trashed
pointers; common underlying problems are running off the end of an array
and trashing other variables, forgetting to initialize a pointer before
using it, or continuing to use a memory area after handing it to free().
