Description:
------------
Reported to the libsodium-php repository too. Just wanted to make sure the PHP team is aware of the issue and hopefully can include the fix in 7.3.1.

https://github.com/jedisct1/libsodium-php/issues/186
https://github.com/jedisct1/libsodium-php/pull/187

Test script:
---------------
<?php

function foo()
{
    throw new SodiumException('test');
}
foo();


Expected result:
----------------
PHP Fatal error:  Uncaught SodiumException: test in /home/scott/sodium_compat/segfault.php:5
Stack trace:
#0 /home/scott/sodium_compat/segfault.php(7): foo()
#1 {main}
  thrown in /home/scott/sodium_compat/segfault.php on line 5

Actual result:
--------------
Segmentation fault (core dumped)

Sorry, got my wires crossed on the actual cause. Earlier I suspected memzero and wrote the wrong thing in the ticket title.

This is happening with PHP 7.3 from Ondrej's PPA, but 3v4l.org is not reproducing the crash: https://3v4l.org/io3Gd

What follows is the output of `strace php segfault.php`, in case it's helpful:

It seems the problem is that zend_hash_clean() is called[1] on a
hash table with refcount==2, which is not allowed:

    php: /mnt/c/Users/cmb/php-dev/php-src/Zend/zend_hash.c:1521: zend_hash_clean: Assertion `(zend_gc_refcount(&(ht)->gc) == 1) || ((ht)->u.flags & (1<<6))' failed.
    Aborted (core dumped)

Also `Z_TYPE_P(frame) == IS_ARRAY` looks fishy; shouldn't that be
`Z_TYPE_P(args) == IS_ARRAY`?

FYI the 3v4l failure (to crash) was caused by sodium not being loaded correctly which I fixed - therefore making this test fail there as well
