IIRC, .NET does something similar for OutOfMemoryExceptions. The exception is thrown before actually running out of memory. That allows just enough space for the OutOfMemoryException object (and associated exception info) to be allocated.

Iirc also perl does this. I’m on the phone right now, but iirc $^O was a variable filled with about 20k of worthless data that could be freed in case of an out of memory condition.

It's called $^M, and you have to explicitly fill it with garbage.

I believe the runtime preallocates an OOME on startup, so if one is encountered it can just fill in the blanks and throw without needing any additional allocations.
