If you use the "default" signature out of the password file, the code
which conses up the signature out of the struct passwd neglects to
null-terminate the signature.
On systems where the stack segment isn't cleared to all zeros before
main() is called, this results in random garbage appended to the
signature.
Adding a "*cp++ = 0" right before "signature = sigbfr;" around line
201 of zwrite.c should fix it.
