    Problem Summary TSD5TH.00089 The code for the above looks like this pthread_t T1_tid; test1() { . . t1_f1( &errors, &fails ); . . } t1_f1( int *errors, int *fails ){ . . rval = vsth_pthread_create( &T1_tid, NULL, t1_t1, NULL ); ....
    Problem Text
    The code for the above looks like this

    pthread_t T1_tid;

    test1() {
    .
    .
    t1_f1( &errors, &fails );
    .
    .
    }

    t1_f1( int *errors, int *fails ){
    .
    .
    rval = vsth_pthread_create( &T1_tid, NULL, t1_t1, NULL );
    .
    .
    }

    t1_t1( void *arg ){
    .
    .
    if ( pthread_equal( T1_tid, pthread_self() ))
    tval = NULL;
    .
    .
    }

    This failure occurs because it is possible for thread t1_t1 to begin and
    end execution before the vsth_pthread_create() in t1_f1() returns. Thus
    the global variable T1_tid isn't set until after pthread_equal() execution
    in t1_t1. Adding a sleep to t1_t1 causes the test to always pass.
