Right, how do we fix it?  Does changing:

BOOST_ASSERT(rep->next.p != 0);
BOOST_ASSERT(rep->alt.p != 0);

In perl_matcher_non_recursive.hpp, line 1043

To:

BOOST_ASSERT(rep->next.p);
BOOST_ASSERT(rep->alt.p);

Fix the issue?

Oh no wait, that can't be done because of this issue: 
http://64.233.183.104/search?q=cache:Aqknf5ncceYJ:lists.boost.org/MailArchives/boost-users/msg06614.php+BOOST_ASSERT+regex+site:lists.boost.org&hl=en&gl=uk&ct=clnk&cd=1&client=firefox-a

This is already the fixed version :-(

Are you able to try with gcc-4.0.1 or later?  I'm pretty certain this is a 
compiler bug, as:

assert(my_pointer_type != 0);

should compile, whether we're in pedantic mode or not.

Otherwise we're going to be adding more BOOST_WORKAROUNDS :-(

Thanks, John.
