coexist with pthread

Hi,

Is it inherently impossible that state-threads coexist with pthread?=20
I am trying to execute a test program shown below.  Is there anyone to
make a similar attempt?

Results:

   Linux 2.4.* Linuxthreads: SEGV
   FreeBSD 4.* libc_r: Fatal error '_longjmp()ing between thread
contexts is undefined by POSIX 1003.1'
   WinXP Cygwin: Runnable(!)

Program:

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

static void *p_thread(void *arg)
{
=09while (1) {
=09=09printf("child pthread [%p]\n", pthread_self());
=09=09sleep(5);
=09}
=09return NULL;
}

static void *s_thread(void *arg)
{
=09while (1) {
=09=09printf("child sthread [%p]\n", st_thread_self());
=09=09st_sleep(5);
=09}
=09return NULL;
}

int main(int argc, char *argv[])
{
=09pthread_t pth;
=09st_thread_t sth1, sth2;

=09pthread_create(&pth, NULL, p_thread, NULL);
=09printf("parent pthread [%p]\n", pthread_self());

=09st_init();
=09sth1 =3D st_thread_create(s_thread, NULL, 0, 0);
=09sth2 =3D st_thread_create(s_thread, NULL, 0, 0);
=09st_sleep(100);
=09return 0;
}
