Subject: Re: [OMPI users] MPI_Allgather with derived type crash

I've tried on my home Ubuntu 10.04, 64 bit version. It crashes with number
of ranks 5-7, 9 and greater. I simply downloaded 1.4.3 version (
http://www.open-mpi.org/software/ompi/v1.4/downloads/openmpi-1.4.3.tar.gz):

- configure --prefix=`pwd`/install && make install
- cd ~/projects/gather
- ~/projects/distribs/openmpi-1.4.3/install/bin/mpicc -o gather ./gather.c
- ~/projects/distribs/openmpi-1.4.3/install/bin/mpirun -n 9 ./gather
- crash!
