If anyone's mail gets bounced back, it's because the account-name here
has changed (see below).

The consensus of opinion is the environment is getting trashed. I'm going
to have to see what I can do with "dbx". It's strange that the environment
is getting trashed when I don't pass **envp to the program, and I never
attempt to do anything to the environment via a system() call.
Since I've received a note that I'm not the only one to have noticed this,
I'm including the following response I received for everyone's benefit:

As I stated in my original posting, everything works fine and as
expected when I type the command line in system() to either csh or sh.

Don't think I could overwrite **envp (see above). Also the code I'm
using generates no complaints from lint (the first thing I did when
I started having problems). Also, the code had previously worked fine
under 2.9BSD and Ultrix V1.2 ...
I've tried to do system("printenv"), but that too generates the error.
So, I'm left with poking around with "dbx" until I find out what is
going on.
Thanks to everyone who responded so far.
