Are you sure?  I suspect it's crashing inside print_msg.

sprintf() returns the resulting string on some, but not all, systems.
Not having access to a VMS machine to try this out on, I suspect
sprintf() there is returning something else - zero, or the number of
characters written, or some such.  Try instead

   sprintf(buf,EOPEN,"startup",startup_file);
   (void) print_msg(PERROR,"init_files()",buf);

which should work everywhere.

If that doesn't fix it I have no more ideas and would have to plunge in
with a debugger.
