Herald added a reviewer: Szelethus.
Herald added a project: clang.

The validity checks are performed in precall callback.

Semantic of checking for opened stream has changed:
It is not allowed at all to use the stream after 'fclose'.
This is what cppreference.com says at fclose.
So the double-close error changes to use-after-close.
