Yes we are using oracle and --enable-sigchild.
--enable-sigchild is not in use on the 4.3.3 install I tested.

Are you using --enable-sigchild ?
If so, and you're not using Oracle, turn it off.

Description:
------------
version 4.3.7 proc_close() and pclose() are not returning proper exit
status codes from spawned processes.
Reproduce code:
---------------
$cmd = "rsync /pinky /brain";
## proc_ method
$setup = array( 1 => array("pipe", "w"));
$process = proc_open($cmd, $setup, $pipes);
if (is_resource($process)) {
while(!feof($pipes[1])) {
echo fgets($pipes[1], 1024);
}
fclose($pipes[1]);
$rv = proc_close($process);
echo ":: proc_close() method ::\n";
echo "exit val: $rv\n\n";
}
## popen() method
$phnd = popen("$cmd", 'r');
while (!feof($phnd)) {
$in = fread($phnd, 2048);
echo $read;
}
$rv = pclose($phnd);
echo ":: pclose() ::\n";
echo "exit val: $rv\n\n";
Expected result:
----------------
## PHP 4.3.3 ##
link_stat /pinky : No such file or directory
rsync error: some files could not be transferred (code 23) at
main.c(620)
:: proc_close() method ::
exit val: 23
link_stat /pinky : No such file or directory
rsync error: some files could not be transferred (code 23) at
main.c(620)
:: pclose() ::
exit val: 23
Actual result:
--------------
## PHP 4.3.7 ##
link_stat /pinky : No such file or directory
rsync error: some files could not be transferred (code 23) at
main.c(620)
:: proc_close() method ::
exit val: -1
link_stat /pinky : No such file or directory
rsync error: some files could not be transferred (code 23) at
main.c(620)
:: pclose() ::
exit val: -1
