#1973 imm: IMM test returns zero even when it fails

[Hung Nguyen]

Snippet from main() in immtest.c

int main(int argc, char **argv) 
{
    ...

    /* Added pthread_exit() to remove dlopen@@GLIBC leak from valgrind */
    pthread_exit(NULL);

    return rc;
}

pthread_exit() should be removed because it makes the test exit before 'return rc'.
I tried to run valgrind without pthread_exit(), it didn't complain anything about dlopen.
