If the count on the first line of the discuss acl file is greater than
the number of lines in the file, discussd dumps core.
Here is a stack trace from a 7.3 VAX:

0xc15a5ed0 (the value of r11) is *(int *)4.
An unfortunate side effect of a text format acl file is that people
are tempted to edit the file manually.
