Description:
------------
On PHP 6 VC 6 from 3.sept.2009 the shell_exec command is broken.

Tested on Xampp on Windows XP with Apache 2.2.9.

Whatever you put into shell_exec e.g.
shell_exec("dir C:\\") 
produces a

Warning shell_exec() [function.shell-exec]: Unable to execute 'dir c:\'

The same script works fine on PHP 5

Also broken in PHP Version 5.2.10; safe mode off.

An earlier version (no record of which) did work when used thus to get a Windows dvd volume label:

if (preg_match('#Volume in drive [a-zA-Z]* is (.*)\n#i', shell_exec('dir '.$drive.':'), $m)) {
    $volname = ' ('.$m[1].')';

I can't reproduce it with php6 neither with 5.3 or 5.2 in CLI or FCGI.

Can you try it with CLI/CGI too please?

Windows, today snaps.

Try with a recent snap please

Yes you are right.
In the build from 22.sep.2009 this bug is fixed.
