Re: [Boost-users] boost::regex: Unexpected behaviour

However, changing line 18 to: if(regex_match(lexical_cast<string>(match[2]), match,

REPORT_DATA_ITEM)) {

and thus eliminating the temporary variable tmp, results in the

following

output:

kW kvar 1090618220000 0008 15 1: (1.5.0)(kW)(5.5.0)(kvar)(8.5.0)(kvar) 1: 1:

What might be the problem here? Am I misusing the match_results class in some way?

Thanks for any help and best regards Pascal

match_results stores iterators into the original string. The string returned from lexical_cast goes out of scope as soon as regex_match returns, therefore invalidating the iterators in match_results. HTH Andrew
