However Windows has stacks that commit on-demand, which is kinda similar to overcommit. It can result in programs terminating on any random function call (if that call requires allocating a new page of stack). https://learn.microsoft.com/en-us/windows/win32/procthread/t...

However this is very rare to happen in practice -- stack growth isn't very frequent in typical applications; so usually a malloc() will fail first in low-memory situations.

A Windows program can avoid the risk of getting terminated on stack growth by specifying equal commit and reserve sizes for the stack. So in least in theory, it's possible to write a windows program that is reliable in low memory situations.
