WSOD Memory Leak when used via HTTPS (SSL)

I can reliably reproduce this issue.

I have apache with an SSL enabled site. Upon activating CKEditor and navigating to https://my.dom.ain/admin/build/block/add I am greeted with a White Screen Of Death (WSOD) and my server's memory is wiped out via what seems to be a leak. PHP's memory limiting system does not prevent the entire server memory, including swap, to become allocated in the space of a few seconds. The browser waits until the server memory is completely used before returning the white screen.

To clarify that it is an interaction between SSL and ckeditor I have multiple other sites running the same module (exact same install from the same directory in ./sites/all/modules/ckeditor), and these all work fine without SSL. Further, I have disabled every module _except_ ckeditor and still reliably get the error condition. Upon deactivating ckeditor the add block page pops up willingly. And reactivating all my modules except ckeditor does not trigger the error.

All this means that ckeditor combined with ssl is the crux.

If you need any more info, please let me know and I'll do my best.
