Description of problem:

The newest redhat kernel comes with a vfork implementation that returns 0 to
both child and parent this could cause programs that use vfork to crash or to
malfunction

Version-Release number of selected component (if applicable):
2.4.20-18xxx

Additional info:
Workaround:
Add /usr/lib/vfork.so to /etc/ld.so.preload and create a shared library with
this source code:
#include <sys/types.h>

pid_t vfork(void) {

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
