6494	Using BOOST_DATE_TIME_POSIX_TIME_STD_CONFIG flag ruins date_time library under MinGW	death.iron.bug@…	az_sw_dude	"I've built static boost libraries under windows (Win7 64) with MinGW 3.20 (32 bit, GCC 4.6.1) with '''BOOST_DATE_TIME_POSIX_TIME_STD_CONFIG''' option and threading=multi link=static runtime-link=static address-model=32

Simple test like
 

{{{
#include <iostream>
#include <boost/thread/thread.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>

using namespace std;
using namespace boost;

void func()
{
    this_thread::sleep(boost::posix_time::milliseconds(5000));
}

int main()
{
     thread trd(func);
    trd.join();
    cout << ""wait ok"" << endl;
    return 0;
}
}}}

When built statically with '''date_time''' and '''thread''' libraries.

It fails with segfault in date_time library. That happens in ctor of structure simple_time_rep, but I didn't dig too much. I guess the problem is in date_time library.

Without flag '''BOOST_DATE_TIME_POSIX_TIME_STD_CONFIG''' it's going all right with timings and threads. 

I also tried flags BOOST_HAS_WINTHREADS and _REENTRANT(for MinGW) - that does not affect the case. BOOST_THREAD_USE_LIB was defined (to let it work with static libs).

I've tested this for boost '''1.48.0''' and '''1.49.0-beta1'''. Neither did work. 
I asked about this problem in boost mailing lists but got no answer, so I post it as a possible bug.
