My new msys2 animal fairywren has had 3 recent failures when checking
pg_upgrade. The failures have been while running the regression tests,
specifically the interval test, and they all look like this:
2019-10-03 05:36:00.373 UTC [24272:43] LOG: server process (PID 23756) was
terminated by exception 0xC0000028
2019-10-03 05:36:00.373 UTC [24272:44] DETAIL: Failed process was running:
INSERT INTO INTERVAL_TBL (f1) VALUES ('badly formatted interval');
That error is "bad stack"
The failures have been on REL_12_STABLE (twice) and master (once).
However, they are not consistent (REL_!2_STABLE is currently green).
The interval test itself hasn't changed for m ore than 2 years, and I
haven't found any obvious recent change that might cause the problem. I
guess it could be a comoiler bug ... this is gcc 9.2.0, which is the
current release.
cheers
