According to FAQ fan John C., there is:
I'm noticing a bug with the US version of OFP - during the mission "Strange Meeting" (the one that you get if you fail the "Montignac Must Fall" mission), if the medic survives the initial encounter (the one immediately after disembarking the truck), he will not run into the woods with the rest of your squad. He will just wait on the edge of the forest. When everyone else in the squad dies, he will become the leader and the game will essentially be stuck. It cannot progress any further with him alive. The jeep in the village will not be drivable and you will not be able to get to the second evacuation point on foot ( I tried both). The only way around this is to kill the medic yourself, at which point, the mission will be winnable again.
On top of that, if the leader survives the encounter in the woods but is injured, he will go back to the medic and also become stuck. There is no need to kill him too, just the medic, at which point, the leader will proceed on. Needless to say, killing the medic doesn't help your mission score too much.
I have duplicated this 3 times on my home computer.
