Hi,

I am using boost 1.37 on osx from macports and I have a problem using the
regex library with gcc 4.4, although it seems to work perfectly with gcc 4.3
and 4.2.

The problem is with creating a boost::regex object- simple program below:

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

int main(int argc, char **argv)
{
  std::string s("(.*)bar|(.*)bah");
  boost::regex re_node(s);
  return 1;
}

The backtrace it produces is below:

(gdb) bt

(gdb)

Is this a problem with boost, or with the compiler? Any ideas for a fix?

many thanks,
