[erlang-bugs] Minor issue: Bad arity display for crypto:hash_update in R16-B03-1

use of recommended functions.

Use of crypto:hash_update/3 is recommended in a warning message , but arity
of crypto:hash_update is 2 (not 3).

 

Example:

Erlang R16B03-1 (erts-5.10.4) [source] [async-threads:10]
[kernel-poll:false]

 

Eshell V5.10.4  (abort with ^G)
