Package: openmpi-bin Version: 1.6.5-9.1 Severity: normal Dear Maintainer,
When upgrading from Jessie to > Jessie, there is a potential for problems with openmpi-bin due to an incorrect dependency on libhwloc5. If one installs libhwloc5 >= 1.11.0 from > Jessie onto a system with openmpi-bin from Jessie, mpirun will segfault in MPI_Init. Hence the dependency libhwloc5 (>= 1.10.0) should also have a conflict libhwloc5 (>= 1.11.0) Yes, I am aware of the fact that this is an unusual situation: it needs one to make a partial upgrade as otherwise openmpi-bin gets updated, too, but many people to cherry-pick newer versions from testing to their stables. In my case, I wanted libdolfin1.5 (not hwloc), which pulled a newer hwloc, but since the Conflicts: was not there, I was left with a sigsegving mpirun. Just for curiosity, the backtrace and symptoms are IDENTICAL to #790540 but the fix (or does it actually happen to be just pure luck?) there does not help here.
