Subject: [Boost-users] Problem using Boost regex

If my previous post makes it to the mailing list, please ignore it
(I figured out some of the original confusion). Here's the problem
I'm left with:-

A couple of days ago I installed libboost (v1.40) using the Windows
setup.exe file. To get myself started I decided to build the regex example
that I found here:-

My installation contains DLLs called:-


along with their associated link libs - and here's the example, as
I built it:-

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

using namespace std;
using namespace boost;

bool validate_card_format(const string s)
      static const boost::regex e("(\\d{4}[- ]){3}\\d{4}");
      return regex_match(s, e);

// and further on, I call the above function....

bool bb = validate_card_format("1111 2222 3333 4444");

If I link my app to boost_regex-vc80-mt-gd-1_40.lib (or if I don't link it
to boost at all) the app won't run. In either case if I try to launch my
app I see a dialog box telling me that the configuration is incorrect
(possibly a problem with manifests?)

OTOH If I link my app to boost_regex-vc80-mt-1_40.lib, I get a crash at the
above call - i.e. at 'bb = validate_card_format("1111 2222 3333 4444");'

The crash is caused by an unhandled exception in 'basic_regex::assign'. The
exception occurs at the call to 'do_assign()' and I get this message:-

> at memory location 0x0012f4e4.

I'm guessing that I should have configured something between installing
boost and starting to use it. Have I missed a step out somewhere?
