LGTM, just please use some other function name than error, error is a glibc
function and it is unnecessary to override it with something unrelated.
Also, patches should go to gcc-patches...

Actually the fix may not handle unaligned addresses properly. I think we should
rather stick with start and end bytes for memory regions in builtins. What's
your opinion?
