I have a problem when trying to use gdb in  mpich-3.0.4

MPICH is configured with:
./configure --prefix=/homes/fisaila/software/mpich --enable-g=all
--enable-fast=O0 --enable-shared

When running a the cpi from examples directory with:
mpiexec -np 1 xterm -e gdb cpi

I am getting the xterm window correctly and:

(gdb) r
Starting program: /nfs2/fisaila/software/mpich-3.0.4/examples/cpi
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

MPID_Init(139).......: channel initialization failed
MPID_Init(421).......: PMI_Get_appnum returned -1
[Inferior 1 (process 14215) exited with code 01]

The gdb version is:
gdb -v
GNU gdb (Ubuntu/Linaro 7.4-2012.04-0ubuntu2.1) 7.4-2012.04

Any suggestion?
