SplObjectStorage debug handler mismanages memory #18322
Description
Description
The following code:
<?php
$stor = new SplObjectStorage();
$obj = new stdClass;
$stor[$obj] = 1;
$tmp = $stor->__debugInfo();
$tmp2 = $tmp[array_key_first($tmp)];
unset($tmp); // Drop $tmp2 RC to 1
$tmp2[0]['obj'] = new stdClass;
var_dump($tmp2);Resulted in this output:
A bunch of ASAN crap
But I expected this output instead:
Not that
The problem is that the code uses a hack rather than properly managing memory: Z_ARRVAL_P(&tmp)->pDestructor = NULL;...
