shared variable

[Nicolas Vignal <nicolas dot vignal at netline dot fr>]

Hello

I know that shared variable must be lock. But behaviour of software under 
debugger and reality should be the same. If you try this little code under 
the last linux gdb snapshot you will see a difference.

On console I have :

I create the thread number 1026
I am the thread number 1026

Under gdb :

I am the thread number -1
I create the thread number 1026

#include <stdio.h>
#include <pthread.h>

pthread_t threadID=-1;


int function(void)
{
  printf("I am the thread number %d\n",threadID);

  while (1);

  return 0;
}


int main(int argc, char *argv[])
{

  pthread_create(&threadID, NULL, function, NULL);
  printf("I create the thread number %d\n",threadID);

  return 0;
}
