--- Comment #1 from Geoff Keating <geoffk at geoffk dot org> ---
A PCH file is a trusted input, so this really shouldn’t happen, and there are
surely many other ways to trigger arbitrary code execution if you can craft
one.  However a sanity check would do no harm, this code is not performance
relevant.
