6029	Boost.Regex incompatible with G++'s Profile features	Akim Demaille <akim.demaille@…>	Daniel James	"Using a recent G++ (say 4.6), it is possible to enable libstc++ features to profile the use of STL features (see http://gcc.gnu.org/onlinedocs/libstdc++/manual/profile_mode.html).  Boost.Regex (and maybe other libraries, I don't know yet) is not compilable with it:
