That's good to know. Is it possible to port that code into
DMD ? How many C libraries do you think are prepared for
exceptions ? They might have to clean up memory or system
resources.

If with @nothrow you mean the nothrow keyword, it has no value
for compiler backends, because assert errors can be thrown
anyways. But I probably misunderstood you.
