Milestone:  Boost 1.42.0  |   Component:  None        
  Version:  Boost 1.41.0  |    Severity:  Showstopper 
 Keywords:                |  
--------------------------+-------------------------------------------------
 I recently upgrade to boost 1.41 (was previously 1.40).  After the
 upgrade, the following code does not compile:

 {{{
 #include <boost/xpressive/xpressive.hpp>

 int main(int argc, char * argv[])
 {
     boost::xpressive::sregex rex =
 boost::xpressive::sregex::compile("test");
     return 0;
 }
 }}}

 Here is the compiler error output:
