Description:
------------
Apparently this has something to do with the environment-variables in
the shell, popen uses to execute the command. If I replace "echo FOO"
with "export" I get the whole line of variables and then it fails,
whereas the successful execution only has one, BASH=/bin/sh. I use php
-n so no php.ini is used.

Reproduce code:
---------------
<?php
$pp = popen("echo FOO", "r");
echo fread($pp, 4096);
var_dump(pclose($pp));
?>


Expected result:
----------------
FOO
int(0)


Actual result:
--------------
FOO
int(-1)
