I'm not worried about a security issue here because in practice this should work out the way we naively expected, we're just making things explicit to the compiler with the casts. 0: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=8876 Differential Revision: https://phab.mercurial-scm.org/D3729
