The debian is a 32 bits Intel p4-M processor (it's my laptop). The AMD machine has a Red Hat Enterprise Linux AS release 4 (Nahant Update 2).

Arghhhh, it's a 64 bits machine where everything is compiled in 32 bits mode ... the default compiler picked up by ompi configure is a 32 bits compiler. So yes it was working as everything get compiled in 32 bits mode.

I do. I'm using gcc4.0.1 on my debian unstable version and a custom
build from the latest gcc CVS on MAC OS X. I run some tests yesterday
on a AMD Opteron(tm) Processor 246 machine (we just have one of them
so I just test fork pls and shared memory BTL) and it worked.
Otherwise most of the clusters I have access to are running with some
version of Redhat (most of them starting with 7.2 and up to fedora
something).
