> Handling OOM gracefully - i.e. doing anything other than immediately crashing and/or invoking undefined behaviour - is absolutely not the default in C.
What are you talking about? Every allocation must be checked at the point of allocation, which is "the default"
If you write non-idiomatically, then sure, in other languages you can jump through a couple of hoops and check every allocation, but that's not the default.
The default in C is to return an error when allocation fails.
The default in C++, Rust, etc is to throw an exception. The idiomatic way in C++, etc is to not handle that exception.
