Bug description:SHMOP not working / crash
Description:
------------
If I make such a intensive read of something saved by shmop, the apache
will
crash.
If it was intensive write, the crash is sooner.
This only happens in Win32 (not in Linux)
Test script:
---------------
<?php
$key = 1;
$value = 1000;
$nbr_of_read_tests = 100000;
$shm_id = shmop_open( $key, "c", 0644, strlen($value));
shmop_write ( $shm_id , $value , 0);
shmop_close($shm_id);
for ($i = 1; $i <= $nbr_of_read_tests; $i++) {
$shm_id = shmop_open($key, "a", 0, 0);
shm_size = shmop_size($shm_id);
$returnedValue = shmop_read ( $shm_id , 0 , $shm_size );
shmop_close($shm_id);
}
shmop_delete($shm_id);
shmop_close($shm_id);
?>
Expected result:
----------------
work without any problem.
In Linux it works.
Actual result:
--------------
Crash of Apache
