#10657: Win32 first time call to GetTimeZoneInformation crashes in launched
coroutines
------------------------------+-----------------------
 Reporter:  vinnie.falco@…    |      Owner:  olli
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  coroutine
  Version:  Boost 1.56.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+-----------------------
 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();
 }
 }}}
