Interestingly, in a fresh docker instance, it seems to patch just fine?

Edit: In docker I'm presumably compiling for Linux only. And apparently the failure doesn't happen on Linux or Windows, but for OSX. So unless the file being patched is OS-specific, I'm not sure why it would fail...

Looks like as you discovered this patch was only used on OS X.
