The same error occurs with others debuggers : totalview, sun dbx, intel idb

I've done the test on 5 Amd opteron x86_64 hosts with Cent OS 5.2
    - The error occurs on 3/5.


RHEL-5.2 kernel was unfortunately very "unfriendly" to the debuggers due to
utrace and the ptrace emulation on top of it.  RHEL-5.3 has all the commonly
visible problems fixed.

I'm waiting centos 5.3 to try the update.
Thnaks a lot !
