10657	Win32 first time call to GetTimeZoneInformation crashes in launched coroutines	vinnie.falco@…	olli	"When an application's first call GetTimeZoneInformation is from a launched coroutine, an unhandled exception is generated. A workaround is to call GetTimeZoneInformation at least once before launching any coroutines. This sample program compiles under Visual Studio and crashes:
{{{
#define _WIN32_WINNT 0x6000
#include <boost/asio/io_service.hpp>
#include <boost/asio/spawn.hpp>
#include <functional>
#include <Windows.h>

TIME_ZONE_INFORMATION tzi;

void die(boost::asio::yield_context yield)
{
    GetTimeZoneInformation(&tzi);
}

int main()
{
    // Uncommenting the following line eliminates the crash
    //GetTimeZoneInformation(&tzi);

    boost::asio::io_service ios;
    boost::asio::spawn (ios,
        std::bind (&die, std::placeholders::_1));
    ios.run();
}
