A rather stable production code that has worked with various versions of MPI on various architectures started hanging with gcc-4.4.2 and openmpi 1.3.33 Which lead me to this thread. I made some very small changes to Eugene's code, here's the diff: $ diff testorig.c billtest.c 3,5c3,4 < < #define

Hi, sorry for the delay but I did some additional experiments to found out whether the problem was openmpi or gcc! In attach u will find the program that causes the problem before mentioned. I compile the program with the following line: $HOME/openmpi-1.3.2-gcc44/bin/mpicc -O3 -g -Wall -fmessa
