I would seriously doubt the crashes you see are do to the latest patch, the things that changed were very simple and minor changes.
I have no doubt that there is a CTD bug currently in the code, the key is when I hear of multiple people having it at one time when they are in the same area.
I currently have no idea what could be causing this crash, I would suspect 1 of 3 conditions.
1. A terrain related issue that is caused by one terrain, possible when when some item on the terrain is destroyed.
2. It is related to how many people or objects are in one area and possibly when a condition is triggered such as some one dies or takes hits, or many weapons are in the air.
3. An issue relating to 1 plane, that when it takes hits in certain area, anyone in vis range of that plane CTD's.
Anyway, any information about the conditions you can think that were surrounding your flight when a CTD happens helps me a lot in trying to determine what the cause is.
