Package: libc6-dev
Version: 2.2.5-11.2

Description: a system function call within a pthread (when statically 
linked) ends the program but leaves the processus zombified
The same problem does not occur on unstable systems (with libc6 2.3.2-4)

Here is a test program that demonstrates the problem, it consists of a 
main function which calls ThreadFunction which itself calls system(const 

/* test.c */
#include <stdlib.h>
#include <pthread.h>
#include <stdio.h>

void* ThreadFunction(void* arg)
    printf("Thread Started\n");

    system("ls -l");

    printf("Thread Stopping\n");

    return NULL;

int main(int argc, char** argv)
    pthread_t thread;
    void* result;
    pthread_create(&thread, NULL, ThreadFunction, NULL);

    pthread_join(thread, &result);

    return 0;
/* END test.c

example of dynamic linking:
# gcc test.c -lpthread -o test
# ldd test
    libpthread.so.0 => /lib/lipthread.so (0x40017000)
    libc.so.6 => /lib/libc.so.6 (0x4002b000)
    /lib/ld-linux.so.2 => (0x40000000)
# ./test
    Thread Started
    ... (output of ls -l)
    Thread Stopping

example of static linkinkg:
# gcc test.c -static -lpthread -o test
# ldd test
    not a dynamic executable
# ./test
    Thread Started
# ps aux | grep test
    root   20027   0.0   0.1   2548   160 pts/1   S   13:26   ./test
    root   20028   0.0   0.1   2548   160 pts/1   S   13:26   ./test

// after launching ./test, Thread Started is printed out, but the 
command prompt shows up immediately and ps sees the processus still running.

if i do this on a machine running 2.3.2-4 or gentoo using  2.3.2 as 
well, the problem does not occur...
i used diiferent compilers with no noticeable change:
# dpkg -l gcc*
    ii gcc-2.95   2.95.4-7
    ii gcc-3.0   3.0.4-7

is this a bug?
is this backportable from the 2.3 series?

oh by the way, uname -a shows 2.4.18-586tsc but fails as well on 2.4.21 
(homemade) and 2.4.22 (gentoo).

Severity: unknown (annoying to me)

have a nice day,

Gabriel Biberian

These bugs are tagged as woody, because they're well-known problems
and for keeping open to come to light what the problem is.  However,
as you know, sarge was released.  Our stable version was moved from
woody to sarge.  It's high time to close old woody's bugs that are
still open.  Now I close these bugs.  If you have any objections to
close them, please reopen and let us know your trouble.
