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:
