tip shell escape (4.3BSD)

[David Brown]

I've been having problems using tip on 4.3BSD.  When I try to use any
tilde command that requires forking a shell (~!, ~$, etc.), I get:

	/bin/csh: permission denied

My environment variable SHELL is set to /bin/csh; when I change this
to /bin/sh, the subshell mechanism works. I've temporarily removed
my .cshrc file; this didn't help.  I've looked at the code
where the fork and execl() are done (/usr/src/usr.bin/tip/cmds.c) and
don't see anything unusual.

The permissions on /bin/csh look normal (755).

Has anyone else noticed this problem?  Any help would be appreciated.

Thanks.
