[Boost-users] Wild Compile Errors with ptime member

I am running Boost 1.33.0 and compiling wiht MinGW.  When I compile
the following source file

=========================
#include "boost/shared_ptr.hpp"
#include "boost/test/test_tools.hpp"
#include "boost/date_time/posix_time/posix_time_types.hpp"

class foo {
public:
    foo() {}
    ~foo() {}
           boost::posix_time::ptime mExecutionStart;
};

class foo_test {
    foo_test();
    ~foo_test();
    void run();
};

void foo_test::run() {
    boost::shared_ptr<foo> testObj(new foo());
        BOOST_CHECK_EQUAL(testObj->mExecutionStart, 
                                          testObj->mExecutionStart);
};
=================================

I get the (lengthy) compiler error output below.  As you can see,
something seems to be trying to log something to an output 
stream.

The test compile just fine as long as the BOOST_CHECK_EQUAL()
doesn't reference a boost::posix_time::ptime variables.

Any ideas?
