Subject: [OMPI devel] Openmpi 1.6.5 is freezing under GNU/Linux ia64
From: Sylvestre Ledru (sylvestre_at_[hidden])

Hello,

In Debian, we are in the process of switching the default MPI
implementation from version 1.4 to 1.6.

Every architectures are fine beside ia64. Any program based on OpenMPI
1.6.5 is freezing.

With a basic test case:
  MPI_Init(NULL, NULL);
  MPI_Finalize();

mpirun -c 4 foo
=> freeze
The backtrace does not show anything.

Does it ring a bell to anyone ?

Thanks
Sylvestre
