Thanks.  Fixed in git master:

  
https://git.savannah.gnu.org/cgit/man-db.git/commit/?id=6230e97a21712c90324c0a414bf873e59f82ce7b

(As far as I know, this only affected configurations that required a
manconv pipe - hence the locale dependency - and that involved an input
file large enough that manconv would mmap it before it had finished
being written and so would need to mremap.  Or something along those
lines.)
