clients segfault on 9.2

Hi,

I have cloned a fresh pg9.2 from github release 7c0fecd and compiled it with

./configure --prefix=$HOME/local --with-openssl && make && make install

The compilation went like a charm in a LXC container running a debian
6.0 with following kernel

Linux java 3.0.0-21-generic #35-Ubuntu SMP Fri May 25 17:58:20 UTC
2012 i686 GNU/Linux

(system that hosts the LXC is an ubuntu).

I have successfuly run initdb and pg_ctl launched the database server
as usual. When I wanted to use any client to the database (psql,
createdb), they segfaulted whatever I used the TCP/IP or unix socket,
all with « trust » authentication in the pg_hba.conf.

Here is a ldd of the psql binary :

$ ldd ~/local/bin/psql
linux-gate.so.1 => (0x00376000)
libpq.so.5 => /home/greg/local/lib/libpq.so.5 (0x008e7000)

libz.so.1 => /usr/lib/libz.so.1 (0x0077d000)

Here is an excerpt of strace's output from the psql segfault (last lines)
$ strace -s 400 ~/local/bin/psql

I know database greg does not exist. This segfaults also when I try to
connect to the template1 database:
...

Is there anything I did wrong ?
