Subject: [OMPI users] OpenMPI bug?
From: Gabriele Fatigati (g.fatigati_at_[hidden])

i have installed OpenMPI 1.2.6, using gcc with bounds checking. But, when i
compile an MPI program, i have many time the same error:

../opal/include/opal/sys/amd64/atomic.h:89: Address in memory: 0x8 ..
../opal/include/opal/sys/amd64/atomic.h:89: Size: 4 bytes
../opal/include/opal/sys/amd64/atomic.h:89: Element size: 1 bytes
../opal/include/opal/sys/amd64/atomic.h:89: Number of elements: 4
../opal/include/opal/sys/amd64/atomic.h:89: Created at:
class/opal_object.c, line 52
../opal/include/opal/sys/amd64/atomic.h:89: Storage class: static
../opal/include/opal/sys/amd64/atomic.h:89:Bounds error: attempt to
reference memory overrunning the end of an object.
../opal/include/opal/sys/amd64/atomic.h:89: Pointer value: 0x8, Size: 8

Setting the enviroment variable to "-never-fatal", the compile phase, ends
successfull. But, at runtime, i have ever the error above, very much time,
and the program fails, with "undefined status".

Is this an OpenMPI bug?
