I noticed that a recent change in gcc with -std=c++0x causes the compilation of
one of my programs to fail. I was using boost regular expressions.
stl_pair:166
#include <iostream>
#include <boost/regex.hpp>
int main()
{
boost::regex expression("^[:space:]*#");
char buf[1024];
while (!std::cin.eof())
{
std::cin.getline(buf, 1024);
std::string sbuf = buf;
if (boost::regex_match(sbuf, expression))
continue;
std::cout << sbuf << std::endl;
}
}
