[Boost-users] upgrade from boost 1.39 to boost 1.50. Issue with regex_match

Hi, I am 'upgrading' a huge C++ app from VS2005 (32bits) to VS2010 (64 bits) and boost 1.39 to boost 1.50. This app runs both under Windows and Linux. In a function that searchs subdirectories and files of a given directory, we get the list of all the elements and then this list is filtered by : if(true==boost::regex_match(sAdaptation, what, childNode.infoNode.rFullPathFilePattern)) sAdaptation is ".\TEST\un_noeud" (this subdirectory exists) childNode.infoNode.rFullPathFilePattern is something like {m_pimpl={...}} And regex_match always returns false. If you can give me information about what is happening ... Jean
