Anyone seen this failure mode before?

qemu : 0.10.50
Target : Qemu-mipsel
toolchain : mipsel-linux-gcc (GCC) 4.2.4

I am attemplting to compile a thead test program in qemu-mipsel. but a thread test program don't work correctly. a thread test program is below

 #include <pthread.h>
 int check_me = 0;
 void* func(void* data) {check_me = 42; return &check_me;}
 int main()
  { pthread_t t;
    void *ret;
    pthread_create (&t, 0, func, 0);
    pthread_join (t, &ret);
    return (check_me != 42 || ret != &check_me);
 }
a check_me value should be 42 and ret address should be same with &check_me, but check_me is 0 and ret address is nil in compiled program in qemu-mipsel.

So I have tested a thread test program in qemu-arm, this test program worked correctly in qemu-arm. 
I don't know why a thread test program don't work correctly in qemu-mipsel.
Is there a problem in qemu-mipsel?
