Bug #81070	Setting memory limit to below current usage
--SKIPIF--
<?php
if (getenv("USE_ZEND_ALLOC") === "0") die("skip requires zmm");
?>
--FILE--
<?php
$a = str_repeat("0", 5 * 1024 * 1024);
ini_set("memory_limit", "3M");
?>
--EXPECTF--
Warning: Failed to set memory limit to 3145728 bytes (Current memory usage is %d bytes) in %s on line %d
Fixed bug #81070 When the memory limit is reduced using an `ini_set("memory_limit", ..)` below the currently allocated memory, the out-of-memory check overflowed. Instead of implementing additional checks during allocation, `zend_set_memory_limit()` now validates the new memory limit. When below the current memory usage the ini_set call will fail and throw a warning. This is part of GH-7040. 2021-05-31 01:30:24 +08:00			`--TEST--`
