zwrite dumped core on me, apparently due to a corrupt malloc pool. This is
repeatable on my workstation only. It looks like a null character was
written over the high byte of the malloc "next block" pointer, causing the
pointer to point at the text segment.

This is the text that causes it to crash. If anyone can answer the
question I'd like that too.
