Well, they could just make them alias of each other, that is not the big deal,
I guess they don't want to waste .rodata space on the data that provides the
details to those functions and waste .text on passing the addresses of such
data to the handlers.  Of course, it would be much harder to understand what is
going on when the functions don't tell you what exactly went wrong (but that is
the same with -fsanitize-undefined-trap-on-error).
