core dump on 8.1 and no dump on REL8_1_STABLE

Hi!

Attached dump cause core on 8.1 release and works fine on REL8_1_STABLE and HEAD.
Am I missed some fixes/commits?


PS dump in KOI8, db should be initialized as
initdb -E KOI8-R --locale ru_RU.KOI8-R -D $DIR
and it should be installed ltree and tsearch2 modules.

PPS gdb output:
