awk bug

[Marnix van Ammers]

While trying to install a new program I ran across a bug in our Sys
V, release 2.1.1 (AT&T 3B20) awk.  In our awk the following pattern
always matches (even if there are 5 or less fields on the current
line):

if $6 != ""

This does not happen on the awk on my 3B1 version 3.51 .

Is this a known bug or what?
