boost::regex only accepts turning off one Perl modifier

Reported by: lpancescu@… Owned by: John Maddock
Milestone: To Be Determined Component: regex
Version: Boost 1.45.0 Severity: Problem

Description

I'm trying to use modifiers with the extended Perl syntax. Turning on multiple modifiers seems to work fine, but turning them off only seems to accept a single modifier after the '-':

#include <iostream> #include <boost/regex.hpp>

int main() {

using std::cerr; using boost::regex; using boost::regex_error;

try {

regex m1("(?xism:
d)", regex::perl); ok regex m2("(?-x:
d)", regex::perl);
ok regex m3("(?-xism
d)", regex::perl); bad regexp

} catch (boost::regex_error err) {

cerr << "Bad regular expression: " << err.what() << "\n";

}

}

I'm using Boost 1.45 from MacPorts? on Mac OS X 10.6.6, trying to "port" some Perl code to C++.
