CASE II landing CTD (Access violation - Flight.dll) - multiple AI in the stack

[kaba]

DCS version: OpenBeta v2.5.6.50321

 

Details of crash:

DCS crashes to desktop during a mission when AI try to land on the carrier.

 

This occurs using both Supercarrier and normal Stennis carrier.

 

I have only experienced this CTD on a Case II landing pattern, and only with multiple AI groups in the stack.

 

The crash consistently occurs as the first AI reaches the downwind leg.

I have reproduced this crash 4 times. Once on a busy mission I made (with supercarrier) oncec on the same mission (without supercarrier) and twice on a test mission with just the supercarrier and AI.

 

Looking at the crash logs, the error is an ACCESS_VIOLATION in relation to Flight.dll.

 

I've attached an excerpt of one of the crash logs below.

Attachments

I've also attached the full logs for the 4 instances of the crash.

 

I have also attached a test mission which reliably leads to this crash. The AI are will try to land at the carrier, and when the first aircraft hits the downwind leg I get the crash. To reproduce, just play the mission, and wait for the AI to land.

 

Hope this helps.
