bug in glibc?

[Dr Alan J Bartlett]

KK,

I am running CentOS 5, update 1 ( == RHEL 5.1) and thought I would mimic your test.

$ uname -a
Linux stxsl 2.6.18-53.1.4.el5.stxsl #1 SMP Tue Jan 8 21:29:57 GMT 2008 i686 i686 i386 GNU/Linux
$ rpm -q glibc
glibc-2.5-18.el5_1.1
$ ldd zxc
        linux-gate.so.1 =>  (0x00343000)
        libc.so.6 => /lib/libc.so.6 (0x00b3d000)
        /lib/ld-linux.so.2 (0x0016e000)
$ cat zxc.c
#include        <stdio.h>
#include        <stdlib.h>
#include        <unistd.h>

main()
{
        int a = 0;

        while (1) {
                printf("XXX(%d)",++a);
                (void) sleep(1);
                if (fork() == 0) {
                        printf("\n");
                        exit(0);
                }
        }
}
$ ./zxc
XXX(1)
XXX(1)XXX(2)
XXX(1)XXX(2)XXX(3)
XXX(1)XXX(2)XXX(3)XXX(4)
XXX(1)XXX(2)XXX(3)XXX(4)XXX(5)
XXX(1)XXX(2)XXX(3)XXX(4)XXX(5)XXX(6)

$ 

You are not alone!

Regards,
Alan.
