even without sanitizers, it is reproducible but with the following
```
<?php
$g = gmp_init(256);
var_dump(gmp_pow($g, PHP_INT_MAX));
```
we get this
```

…reset
The code tries to read the context on NULL when
`php_stream_xport_crypto_setup` fails because by then `stream` is reset
to NULL.
This is also UB, so can cause miscompiles.

Only one of the two arrays (subitem) is destroyed, and critext is not.
This leads to a memory leak if the loop bails out:
```
