The regression tests now fail on a number of tests due to a server crash: 2017-04-08 18:55:19.826 PDT [90779] pg_regress/errors STATEMENT: select infinite_recurse(); TRAP: FailedAssertion("!(((((const Node*)(a))->type) == T_Bitmapset))", File: "bitmapset.c", Line: 601) 2017-04-08 18:55:22.487 PDT [90242] LOG: server process (PID 90785) was terminated by signal 6: Abort trap 2017-04-08 18:55:22.487 PDT [90242] DETAIL: Failed process was running: explain (costs off) select * from onek2 where unique2 = 11 and stringu1 = 'ATAAAA'; This is very near where the original crash reported in this thread was crashing, probably only different due to the extra lines of Assert that were added. Am I missing some portion of the fix that you are testing? I have only applied the patch that Tom included in the previous email. mark -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
