`php_admin_value[extension]=` in FPM pool configuration unsafely runs RINIT

[TimWolla]

Description

With the following configuration:

[global]
log_level = debug
error_log = /dev/stderr

[www]
listen = 9999
pm = ondemand
pm.max_children = 3
php_admin_value[extension]=session.so
catch_workers_output=true

and a small patch to session.c to enable session auto start by default (custom INI flags are not loaded in time, other in-tree extensions do not crash):

It would probably be best to disable php_admin_value[extension] entirely, it already requires zend_rc_debug = false:

php-src/sapi/fpm/fpm/fpm_php.c

Lines 97 to 109 in 38b9c33

	#if ZEND_RC_DEBUG
	bool orig_rc_debug = zend_rc_debug;
	/* Loading extensions after php_module_startup() breaks some invariants.
	* For instance, it will update the refcount of persistent strings,
	* which is normally not allowed at this stage. */
	zend_rc_debug = false;
	#endif
	php_dl(value, MODULE_PERSISTENT, &zv, 1);
	#if ZEND_RC_DEBUG
	zend_rc_debug = orig_rc_debug;
	#endif

Alternatively, since the extension is loaded as MODULE_PERSISTENT rather than MODULE_TEMPORARY, it should just run MINIT + GINIT, but not RINIT? It should also be noted, that for the RINIT during loading there is no matching RSHUTDOWN, which might also result in memory leaks.

Related #9921.

It should also be noted, that for the RINIT during loading there is no matching RSHUTDOWN, which might also result in memory leaks.

Indeed. mbstring triggers:
