Subject: [OMPI users] Signal: Segmentation fault (11) Signal code: Address not mapped (1)
From: Jean Potsam (jeanpotsam_at_[hidden])

Dear All,
               I have installed openmpi 1.3.2 in my home directory ( /home/jean/openmpisof/ ) and BLCR in /usr/local/blcr. I have added the following in the .bashrc file

export PATH=/home/jean/openmpisof/bin/:$PATH
export LD_LIBRARY_PATH=/home/jean/openmpisof/lib/:$LD_LIBRARY_PATH

export PATH=/usr/local/blcr/bin/:$PATH
export LD_LIBRARY_PATH=/usr/local/blcr/lib:$LD_LIBRARY_PATH

I am running my application as follows:

mpirun -am ft-enable-cr -mca btl ^openib -mca snapc_base_global_snapshot_dir /tmp mpitest

But I get the following error when i try to checkpoint the application.
