As far as I'm concerned, this is a "rock solid repeatable"
And I think France '44 is a stock scenario? But it's pretty clear this is not related to the specific scenario, this is something in the code for the game, so there's not really any point in sending someone a save game to have a look at.
I think I've described the issue as well as I can by now, so if nothing else happens there's nothing to do but wait for a fix. Again, this is why a simple "Yes we are aware of it, and looking into a fix" from the people who know the code would be enough to let the issue rest.
Also let it be clear, I'm just helping investigating the issue for the one who originally reported it (Fastfrank), because I think it's an interesting case. I've not experienced the issue myself when actually *playing* the game. I have managed to make it crash *on purpose* to recreate the issue, and this is very much repeatable, independent of specific scenarios.
Confirm as repeatable. The scenario in question eats memory like its going out of style -- every time (this on a W10 machine). I can try running COW on an older machine, but because it uses the Vista OS, I don't if I can get a working copy of the process monitor software that Shadrach used.
