Psql malloc error on Git master

Excerpts from Thom Brown's message of jue ene 20 16:36:10 -0300 2011:

Using 9.1devel as of yesterday's Git branch master, I'm getting an
error in psql when attempting to tab-complete a system tab.

Steps to recreate:

1) From terminal, run "psql postgres" to connect to the postgres
database as the current user.
2a) Type: \d pg_o
2b) OR type: \d pg_op
3) Press TAB to auto-complete

I can't reproduce it here (but this is 64bit). Did you try "make
distclean"?

If you can still reproduce it after that, please try "git bisect" to
find the problem commit.

Known bug in OSX's libedit. Use readline instead.

How do I force readline? I'm not using --with-libedit-preferred or
--without-readline

Do you have it installed?

You may need to fool with the link path to ensure that you link to
a real readline and not /usr/lib/libreadline.dylib (which is just
an alias for libedit).

What I've done is to switch to MacPorts[1]<http://www.macports.org/&gt; and use their packaging. I'm
building PostgreSQL then with:

--with-libraries=/opt/local/lib --with-includes=/opt/local/include

which for example links psql/libreadline with:

% otool -L $PGSQL_HOME/bin/psql
/Users/bernd/pgsql-dev/install/HEAD/bin/psql:
/Users/bernd/pgsql-dev/install/HEAD/lib/libpq.5.dylib (compatibility
version 5.0.0, current version 5.4.0)
/opt/local/lib/libintl.8.dylib (compatibility version 10.0.0, current
version 10.1.0)
/opt/local/lib/libssl.1.0.0.dylib (compatibility version 1.0.0, current
version 1.0.0)
/opt/local/lib/libreadline.6.1.dylib (compatibility version 6.0.0, current
version 6.1.0)

Works quite well for me. There's also a libedit in MacPorts, but i've never
used it.

Okay, I've tried your recommend config options and all seems to be
well now. I'll note that for future builds.

Thanks
