Hi.
Its seems to be impossible to use shmop_write if you are opening memory segment secong time.
example code (produces crash):

$mid = 0xffe;

$shm_id = shmop_open($mid, "c", 0644, 100);
if(!$shm_id) {
        echo "Couldn't create shared memory segment\n";
}
$shm_bytes_written = shmop_write($shm_id, "my shared memory block", 0);
if($shm_bytes_written != strlen("my shared memory block")) {
        echo "Couldn't write the entire length of data\n";
}

shmop_close($shm_id);
$shm_id = shmop_open($mid, "a", 0, 0);
$shm_bytes_written = shmop_write($shm_id, "my shared memory block", 0);
if($shm_bytes_written != strlen("my shared memory block")) {
        echo "Couldn't write the entire length of data\n";
}

shmop_close($shm_id);

I did somehting wrong? or i should use other release of PHP?
