--- Comment #80 from Ilya Konovalov aragaer@gmail.com 2012-10-04 03:07:33 CDT --- The patch changes two things.
1. It enables certificates to keep reference to internal temporary store of intermediate certificates (which are then used to prove validity of site certificate) and allows the clean removal of that store.
2. It alters secur32 to properly initialize that internal temporary store.
Nothing else.
