Dear Sirs:

I am using FreeBSD-2.2.8 and after calling pthread_create()
my programs get sigfault (SIGSEGV) and exited with core dump.

I should like to ask if somebody know the solve of this problem.
My example of using pthread is included below.

I ask to answer me directly on my e-mail.

Oleg

#include <errno.h>
#include <pthread.h>
#include <sys/socket.h>
#include <sys/un.h>

#define socklen_t       unsigned int

static void *coms(void *arg)
{
  pthread_detach(pthread_self());
  write((int)arg, "Test", sizeof("test"));
  close((int)arg);
  return(NULL);
}

int main(int argc, char **argv)
{
  int *confd, len, lisfd;
  struct sockaddr_un *client, saun;

  lisfd = socket(AF_UNIX, SOCK_STREAM, 0); unlink("/tmp/TS");
  saun.sun_family = AF_UNIX; strcpy(saun.sun_path, "/tmp/TS");
  bind(lisfd, (struct sockaddr *) &saun, sizeof(struct sockaddr_un));
  listen(lisfd, 2);

  client = (struct sockaddr_un *)malloc(sizeof(saun));
  confd = (int *)malloc(sizeof(int));
  for ( ; ; ) {
    len = sizeof(saun);
    *confd = accept(lisfd, (struct sockaddr *) client, &len);
    pthread_create(NULL, NULL, &coms, confd);
  }
  return(0);
}
