Oh i am very much sorry, i stuck over an hour on a bug-bash thread
mail, because i could not find the mailing-list thread that
likely resulted in these BSD commits on 2017-07-06; i thought it
was on oss-security, but - no.
I know it was a ML thread because i had to adjust my own thing:

         /* Char after prefix must be valid.  However, after some error
          * in the tor software all libraries (which had to) turned to

So it definetely was tor related by then.  But where?

          * an interpretation of the C standard which says that the
          * prefix may optionally precede an otherwise valid sequence,
          * which means that "0x" is not a STATE_INVAL error but gives
          * a "0" result with a "STATE_BASE" error and a rest of "x" */

Have a nice Sunday!
