5958,Passing an argument of non-POD class type boost::match_results through ellipsis,"""LeJacq Jean Pierre"" <jeanpierre.lejacq@…>",John Maddock,"boost::regex_replace() is implemented using the any_type struct that has a single constructor that has ellipsis as the argument type. The non-POD type boost::match_results is passed to the any_type constructor.

I believe this violates the standard (section 5.2.2 para 7. In particular, ""If the argument has a non-POD class type (clause 9), the behavior is undefined.""

This issue was detected with the IBM compiler XL C/C++ 11.1.0.3 with the following diagnostic:
