Bingo, thanks for the pointer.

Yup, reproduced with "make post-build MALLOC_OPTIONS=J", and valgrind
also has something to complain about, so I'll forward a report upstream.

I haven't seen something in the "maint" branch since the release that
looks like an obvious fix.

This lets 11-CURRENT and redports off the hook for now.  I wasn't aware
redports-on-11 set MALLOC_OPTIONS=J or equivalent.

Cheers,
Matthias
