I cannot explain, so I'm tempted to call it a bug.
Apparently some code looks up the symbol table and if utf8:: is there,
then it does something that usually is only available when utf8 is
loaded. So by actually making sure utf8 is loaded, you give that code
what it needs.
Right. The old assumption was that if the stash for utf8:: exists
then utf8->SWASHNEW can be called. That's obviously wrong.
Unfortunately the fix against utf8.c included in the change 9200
(see below) was not integrated into the 5.6 maintenance track,
though the fix had been integrated into the 5.7 development track
before the release of 5.6.1.
