Hi,

I have written following code -

#include<stdio.h>

void *thread_func(void *data)
{
  printf("In thread\n");
  pthread_exit(NULL);
}

int main()
{
  pthread_t mythread;
  int rc;

  rc = pthread_create(&mythread, NULL, thread_func, NULL);
  if (rc){
         printf("ERROR; return code from pthread_create() is %d\n", rc);
         exit(-1);
      }

  printf("In main..\n");

  pthread_exit(NULL);
}

It must print both "In main" and "In thread".
But sometimes it prints one of these two and sometimes both.
I tried in actual UNIX OS. It always prints both.

I also tried in c++ in cygwin, problem exists there also.

Is anyone aware of this problem and its solutions?

Thanks,
Gaurav
