Package: libc6
Version: 2.3.2.ds1-10
Severity: normal

Minimal test program to demonstrate problem:

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

#define NTHREADS 30

void * thread(void * arg)
{
   return NULL;
}

int main()
{
   int i;
   pthread_t threadid;
   
   for (i=0; i<NTHREADS ; i++) {
      pthread_create(&threadid, NULL, &thread, NULL);
      pthread_join(threadid, NULL);
   }

   printf("Press RETURN: ");
   while (getchar() != '\n');
   return(0);
}

When it prompts for keyboard input, notice how many "defunct" pids
there are.

Expected behaviour appears to happen under libc6 2.3.2-7, and when
running under kernel 2.6.0test9 (the .deb in sid) with or without
LD_ASSUME_KERNEL=2.4.0. It doesn't appear to matter whether I have
libc6-i686 installed.

(I'm not ruling out that it might be a bug in kernel 2.4.22)

glibc 2.5 which is now in unstable has switched to NPTL only, which fixes 
this problem. Closing the bug.
