Well, so I got caught by one of the "Ten Most Common Perl Mistakes".
This one's a little more strange.

I'm trying to unpack a structure that contains binary data.  My template
is like this:

	$STRLEN = 20;
	$struct = "l i i a$STRLEN";

After read'ing a number of bytes and unpacking, the variable that
corresponds to the "a" above doesn't get filled with nulls, it gets
filled with spaces, which I have verified using index.  Using "A"
instead of "A" yields identical results.

Could this be a problem with either read or unpack?

P.S. I'm at patchlevel 18.

P.P.S. Using the -w flag shows no problems.
