When I run 10 copies on the same node with btl tcp,self (no sm or openib),
valgrind reports the following to me (using ompi-1.4 branch HEAD):
==23753== Invalid write of size 1
==23753==at 0x4C6EA31: non_overlap_copy_content_same_ddt (dt_copy.h:170)
==23753==by 0x4C6CC3B:
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
