Subject: [OMPI users] error in (Open MPI) 1.3.3r21324-ct8.2-b09b-r31
From: Lydia Heck (lydia.heck_at_[hidden])

We are running Sun's build of Open Mpi 1.3.3r21324-ct8.2-b09b-r31
(HPC8.2) and one code that runs perfectly fine under
HPC8.1 (Open MPI) 1.3r19845-ct8.1-b06b-r21 and before fails with

[oberon:08454] *** Process received signal ***
[oberon:08454] Signal: Segmentation Fault (11)
[oberon:08454] Signal code: Address not mapped (1)
[oberon:08454] Failing at address: 0
0x0 [ Signal 11 (SEGV)]
[oberon:08454] *** End of error message ***
mpirun noticed that process rank 0 with PID 8454 on node oberon exited on
signal 11 (Segmentation Fault).

I have not tried to get and build a newer Open Mpi, so I do not know if the
problem propagates into the more recent versions.

If the developers are interested, I could ask the user to prepare the code for
you to have a look at the problem which looks like to be in MPI_Alloc_mem.

Best wishes,
