Subject: [sqlsmith] Failed assertion in brin_minmax_multi_distance_float4 on REL_14_STABLE
Date: Thu, 04 Nov 2021 09:46:49 +0100
Message-ID: <87r1bw9ukm.fsf@credativ.de> (raw)
Hi,
sqlsmith triggers the following assertion when testing REL_14_STABLE:
TRAP: FailedAssertion("a1 <= a2", File: "brin_minmax_multi.c", Line: 1879, PID: 631814)
I can reproduce it with the following query on a fresh regression
database:
insert into public.brintest_multi (float4col) values (real 'nan');
The branch was at f6162c020c while testing, backtrace below.
regards,
Andreas
