Bug in xpressive

[pabloh@…]

Hello,

I used to had an old version of boost (I don't remember exactly which) and my code worked fine. Now I updated to the last version and I started to receive compilation errors in linux when using a std::vector with regular expressions from boost::xpressive, in windows it compiles fine. This code doesn't compile:

#include <vector> #include <boost/xpressive/xpressive.hpp>

typedef boost::xpressive::basic_regex<std::string::const_iterator> regex_t;

int main(int argc, char* argv[]) {

std::vector<regex_t> vector; vect.push_back(regex_t());

return 0;

}

Compiler output:

I'm using gcc 4.4.2 and boost 1.41
