    Hello,

    I try to test this program.

    mythread.c

    ======

    #include <stdio.h>

    #include <pthread.h>

    void* mythread (void *arg) {

    int a = *(int *)arg;

    printf ("thread %d start\n", a);

    return ((void *)0);

    }

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

    pthread_t t[100];

    for (int i=0; i<100; i++) {

      pthread_create (&t[i], NULL, &mythread, (void *)&i);

    }

    for (int i=0; i<100; i++) {

      pthread_join (t[i], NULL);

    }

    return 0;

    }

    =======

    I compile by using this command

    "gcc -o mythread -static -I/usr/include/nptl -I/usr/include -L/usr/lib/nptl -L/usr/lib mythread.c -lpthread"

    I run it under GDB, but I don't know where it is error. It generates core dump before execute main function.

    I need all of your help.

    Thanks

    Thanapol R.
