[YuanchengJiang]

Description

The following code:

<?php
try {
} catch (SodiumException $ex) {
echo $ex->getMessage(), PHP_EOL;
}
$a = zend_create_unterminated_string('333');
$b = zend_create_unterminated_string('333 ');

Resulted in this output:

/php-src/Zend/zend_variables.c:63: void zend_string_destroy(zend_string *): Assertion `(str)->val[(str)->len] == '\0' && "String is not null-terminated"' failed.
Aborted (core dumped)

Operating System

This isn't a bug. zend_create_unterminated_string is a test function in the test extension to check whether this assertion works... The test extension exposes internal engine stuff for the test suite and is not used in production.
