What's crashing for me is restoring the (12dev) dumpfile using v11 psql:

[pryzbyj@database tmp]$ pg_restore backup-20190225074600.10361-db-depesz.dump >/dev/null
Segmentation fault (core dumped)
[pryzbyj@database tmp]$ pg_restore -V
pg_restore (PostgreSQL) 11.2

I would restore dump into v12dev and re-dump and compare dump output, except it
seems like pg_restore -d no longer restores into a database ??

[pryzbyj@database tmp]$ PGHOST=/tmp PGPORT=5678 PATH=~/src/postgresql.bin/bin pg_restore backup-20190225074600.10361-db-depesz.dump -d postgres |wc -l
