PG12 Server on crash on creating FTS dictionary

Hi Team,

I've encountered a server crash on creating FTS dictionary with below SQLs:

CREATE TEXT SEARCH TEMPLATE public.ftstemp (
INIT = varchar_support,
LEXIZE = dispell_lexize
);

CREATE TEXT SEARCH DICTIONARY public.mydicttemp (
TEMPLATE = public.ftstemp
);

The logs says:
2020-07-14 15:09:32.350 IST [19671] LOG: server process (PID 73228) was
terminated by signal 11: Segmentation fault: 11

2020-07-14 15:09:32.350 IST [19671] DETAIL: Failed process was running:

2020-07-14 15:09:32.350 IST [19671] LOG: terminating any other active
