Sorry, I just want to add 2 more things:
+ I tried configure with and without --enable-ft-thread but nothing changed
+ I also applied this patch for OpenMPI here and reinstalled but I got the same error
Somebody helps? Thank you very much.

I'm using OpenMPI 1.4.2 with BLCR 0.8.2 to test checkpointing on 2 nodes but it failed to restart (Segmentation fault).
Here are the details concerning my problem:
+ OS: Centos 5.4
+ OpenMPI configure:
./configure --with-ft=cr --enable-ft-thread --enable-mpi-threads \
--with-blcr=/home/nguyen/opt/blcr --with-blcr-libdir=/home/nguyen/opt/blcr/lib \
+ mpirun -am ft-enable-cr -machinefile host ./test
I checkpointed the test program using "ompi-checkpoint -v -s PID" and the checkpoint file was created successfully. However it failed to restart using ompi-restart:
"mpirun noticed that process rank 0 with PID 21242 on node rc014.local exited on signal 11 (Segmentation fault)"
Did I miss something in the installation of OpenMPI?
