--- Comment #12 from Michael Catanzaro <mcatanzaro at gnome.org> ---
My thinking is this: a build failure is inconvenient. Carrying patches in WebKit to fix downstream build failures is also inconvenient for WebKit. If it's a big patch, that's probably too much inconvenience for upstream, and a downstream patch is warranted. If it's a one-liner, it's probably simpler for everyone to take the patch upstream.

But a runtime failure, where WebKit does not behave properly at runtime, is a footgun. We can't possibly expect distributors to patch WebKit to avoid this, because they receive no build warning to notice that anything is wrong. In particular, in this case, we're calling a library function that used to fail unless passed an unsigned char... just adding a cast to unsigned char is not very onerous.
