[CRASH] "Forget About Freeman", pressing Esc in a specific place

In “Forget About Freeman”, in the area where the indoor tank and the marines fight against the Agunts and Vortigaunts inside a garage (photo attached), after killing everyone, I pressed “Esc” to save the game: in that moment, the menu not even showing up, the game crashed.
I reloaded, re-killed everyone, moved on for a few step (but staying always in the same area), and hit “Esc”: the game crashed again. And again.
The same happened also in the hallway parallel to the same garage (where there are 2 turrets at the end). For a total of 4 times in a row.

I went through the area without hitting “Esc”, and when I got far enough, I tried once more: this time, the menu popped up normally.

So I suggest that this weird kind of problem is connected to that specific zone, as it never happened before nor after, but just there, and 4 times in a row: it cannot be a casual thing.

As usual, the minidumps are attached.
