There was a problem quite a while ago with BSD/386 executables.  They
accessed something in the startup code (before main) which isn't
(wasn't?) mapped in FreeBSD, a pointer to ps strings (see page 430 of
"Porting UNIX Software", which by chance mentions this very problem.
I thought the problem had been solved a long time ago--what version of
FreeBSD are you running, and what version of BSD/OS did the executable
come with?
