PostgreSQL version: 8.3 beta3
Operating system: macosx 10.4.10
Description: psql segfault on exit

I just maked/make installed pg8.3b3 from cvs.
Here is a copy of the segfault with the psql and backend versions :

freed object - object was probably modified after being freed, break at

I don't know which other information I could add. Feel free to ask me for
some test/info.

For example: http://archives.postgresql.org/pgsql-bugs/2007-11/msg00128.php Since quite a few people seem to bump into this, I wonder if we could have configure to test for this? -- Heikki Linnakangas EnterpriseDB http://www.enterprisedb.com

(They seem to have fixed it in Leopard, btw.) Recommended workaround is to install libreadline from source (the version in /usr/lib isn't really readline) and recompile with that instead. http://archives.postgresql.org/pgsql-hackers/2006-12/msg01222.php regards, tom lane

Probably not worth the trouble, seeing that Apple has finally fixed the problem in 10.5 --- not tested by me, but a look at their source code on-line shows it's fixed: http://www.opensource.apple.com/darwinsource/10.5/libedit-11/libedit/src/history.c regards, tom lane
