The HCA card is a Mellanox Technologies MT25418 (ConnectX IB DDR, PCIe 2.0
2.5GT/s, rev a0).
I cannot post code/instructions how to reproduce these errors as they randomly
appeared during some tests I've performed to locate the origin of a
segmentation fault during an MPI collective
What HCA card do you have ? Can you post code/instructions howto reproduce

I've been working on a random segmentation fault that seems to occur during a
collective communication when using the openib btl (see [OMPI users] [openib]
segfault when using openib btl).
During my tests, I've come across different issues reported by OpenMPI-1.4.2:
