Description:
------------
My English is poor, just look the php script.
I test php7.3.0 php7.2.3 php7.1.10, all of them cause a segfault in fpm and cli.
Test script:
---------------
<?php
function error_handle($level, $message, $file = '', $line = 0){
$a = [1,2,3];
$b = [3,2,1];
array_multisort($a, SORT_ASC, $b); // if comment this line, no segfault happen
}
set_error_handler('error_handle');
$data = [['aa'=> 'bb',], ['aa'=> 'bb',],];
array_multisort(array_column($data, 'bb'),SORT_DESC, $data); // PHP Warning error
Expected result:
----------------
no segfault happen
Actual result:
--------------
Program terminated with signal SIGSEGV, Segmentation fault.
