[boost] regex_match and temporaries

Using valgrind I found an unexpected behavior in regex_match when using
temporaries. Although the input parameters allow using temporaries for
the string to search in (i was using the variant that takes const
std::string&), actually accessing the matches using a boost::smatch will
try to look up the data in the already destructed temporary.

I could not find a note in the documentation that describes this
limitation, I think some clarification would be good.
