[Sun workstations do not run `Unix 4.3', by which I guess that you mean
`4.3BSD': Sun workstations run SunOS and Mach.  This question should
have been directed to a Unix-specific group, not comp.lang.c; I have
redirected followups to comp.unix.questions.]

You are quite right; the existing Unix debuggers cannot handle programs
that fork.  SunOS 4.0 provides new facilities that make it possible,
but if you are dealing with older Unixes, you must either delete the
fork, or fall back on more `traditional' debugging schemes.
