Re: [boost] [xpressive] Broken in release if explicit operator bool is available

With the recent change to Boost.SmartPtr that adds support for explicit operator bool() Boost.Xpressive no longer compiles. The relevant error message is:

./boost/xpressive/detail/utility/tracking_ptr.hpp:440:73: error: no type named ‘unspecified_bool_type’ in ‘class boost::intrusive_ptr<boost::xpressive::detail::regex_impl<const char*>

...

’

Could this be fixed?

This may be the same as an issue I filed a couple of weeks ago [1]. That has been fixed in trunk, but not merged to release yet. Regards, Nate [1] https://svn.boost.org/trac/boost/ticket/7809
