That's by design. Previously they would die:

It's a mechanic to prevent biters from building up over time and never getting anywhere slowing down the game.

Yeah, but there's no obvious reason for them to do that in the situation in the video.
Please post the save where you can reproduce this situation.

Okay, fixed in 0.12.11.
This was triggered by a piece of code that deletes units like this when they're far away from their spawner and can't return back for some reason. In these cases, we generally want to just remove these units as they would just keep hogging the CPU whilst stuck in some weird place that made it impossible for them to return to their spawner in the first place. The bug was that this code didn't check whether the biter even wants to go back to its spawner, and happily removed biters mid-attack.

Good to hear.
Thank you for this detailed explanation - it is very interesting
