Which seems to be a problem with this particular error reporting mechanism,
but no principle problem.
For example, in C++, the bad_alloc exception does not have such a problem.

I would say it is even more important that out-of-memory does not abort(),
because out-of-memory situations can happen without being caused by
an application bug (e.g. in contrast to API contract violations).
