Comment:

 How about I prepare a sanitizer blacklist file to go in contrib/clang, and
 then document it in doc/HACKING?

 Now that I know how it works, I'll also prepare another blacklist for
 curve25519-donna.c, as it also uses undefined behaviour. (At least until
 we fix #13538.)

 That way, all the known undefined behaviour in the codebase is documented
 in the one place.

 I'll work on a patch for it.
