Update from 4.3.1 to 4.4 stuck at blank do-core-upgrade when SCRIPT_DEBUG and FORCE_SSL_ADMIN are set to true

[ElastisysLars]

I had the following settings in my wp-config.php:

define('FORCE_SSL_ADMIN', true);
define('SCRIPT_DEBUG', true);

With those settings, the update to 4.4 failed. I got a completely blank, content-free page at the do-core-update step. Going to the location bar in my browser and hitting Enter brought up a page asking me if I was sure I wanted to continue, but gave me no buttons to do so.

When I commented the lines out from my wp-config.php file, the update could be successfully applied.

I sincerely hope that it is the SCRIPT_DEBUG one that made it fail, and not the SSL_ADMIN one, but I am not well-versed enough in WordPress (or PHP) to do the detective work required.

Have you tried only commenting out the SCRIPT_DEBUG line (or only FORCE_SSL_ADMIN) and performing the upgrade?

Due to strangeness with my setup (#34912), I must have them either both set to true or both false. Sorry.

Unfortunately I wasn't able to duplicate this, and without further reports I can't see what's closing it.

I'm marking this as invalid for now, but feel free to re-open if others experience it.
