Tha program that hits a malloc failure will not necessarily be the program that ate up all the RAM.

Malloc failure is at least synchronous with the out of memory condition. And if your program has reached a fixed state, it may not even be calling malloc.

Ot: your flak blog could benefit from a page showing links to all articles. Currently, hard to read beyond 'recent'.

Sure, but (a) it can handle the malloc failure and (b) it's pretty easy for the user to find the bad guy.

It might handle the malloc failure by crashing. Some languages (e.g., Rust) and runtimes (e.g., glib) presume that small allocations always succeed; a failure in such an allocation immediately crashes the program (as the underlying API provides no means to report the failure).

Rust the language doesn't know anything about allocation; it's entirely a standard library decision.

(a) it probably won't therefore (b) the "bad guy" is going to be most/all processes.
