   Are you absolutely, 100% positive that the above occurs with FreeBSD 2.1.0-
RELEASE?
   I ask this because I fixed the above bug long before the release:


symbolic names:
        RELENG_2_1_0_RELEASE: 1.3.4.1
...
----------------------------
revision 1.4
date: 1995/09/20 08:30:56;  author: davidg;  state: Exp;  lines: +3 -2
Don't dereference a NULL pointer in the case of a null pipe.
e.g.:
ls |> foo.out

sh now behaves the same as it does under SunOS 4.x for this case.

revision 1.3.4.1

Brought in change from rev 1.4: don't dereference a NULL pointer in null
pipes.
