[Boost-users] [Regex] regex_match changed to match_any in 1.33?

In boost/regex/v4/regex_match.hpp, a number of the overloads (the ones that don't take a result parameter) are now bitwise-oring in regex_constants::match_any. As a result, a sequence like boost::regexp exp("a(bc)?") char *value = "abcbc"; bool result = boost::regex_match(value, value + 5, exp); will now set result to true where it was previously false in 1.32. I fixed our code by passing in a dummy result object as an extra parameter. Was this change intentional? I couldn't find any documentation that mentions it. JVS
