i wrote a test code:

void worker(int firstNumber)

      Thread.sleep(1.msecs);
}

void main()
{
     foreach (i; 1 .. 1000) {
         spawn(&worker, i );
         writeln(i);
     }
     thread_joinAll();
     writeln("ok");
}


sometimes it's ok,sometimes it's crashed ! why ?
here is one of times callstack message:

  	test.exe!_free()	
  	test.exe!_fwide()	
  	test.exe!_fwide()

That sounds like a bug in stdio. fwide is the horrible attempt of C 
stdio to do wide character output.

thanks,you are right.

window console show chinese char is not right,
so i try to add this code:
"
extern(C) int setlocale(int, char*);
static this()
{
     fwide(core.stdc.stdio.stdout, 1);
     setlocale(LC_CTYPE, cast(char*)"china");
}
"
it's looks like solve the problem,but caused another problem.

now i use "chcp 65001" command to change the code page and change 
the
font to "lucida console".it works correctly!

this way also have problem!
look this bug report:
Issue 13651 - Writing Unicode text with console code page 65001
(UTF-8) may fail

now,i use this code show string on window console:

void write(string s)
{
      import std.windows.charset:toMBSz;
      printf(toMBSz(s));
}
void writeln(string s)
{
      write(s);
      printf("\r\n");
}
