I find it totally bizarre that PHP (or at least your version of it)
didn't short-circuit the expression as it should.  Anyway, it's
funny you should mention it as I just revised the StopWatch function
on Thursday in a way that would alleviate this particular problem
(it'll appear in the next release).

This is another of those situations where it must be something unique
to the PHP configuration you're using, as the crypt() function has been
available since PHP 3.  Anyway, the easier workaround here it to
provide a custom crypt() as I outlined in my earlier email.

Definitely related to the problem with crypt -- without crypt,
PmWiki doesn't have any way to encode/store/compare its passwords.
