Package:libopenmpi2 Version: 2.1.1-6+b1 A mpi user here cannot run his program because of this error:
Read -1, expected 60480, errno = 38 His program works in 2 other machines with [much] older versions of openmpi. One of them runs Debian sid with libopenmpi1 version 1.6.5-11. The machine where the error appears runs Debian sid with the latest version: libopenmpi-dev 2.1.1-6+b1 libopenmpi2 2.1.1-6+b1 openmpi-bin 2.1.1-6+b1 I found in https://github.com/open-mpi/ompi/issues/3821 that a patch commited in July 11 may fix the issue. The changelog shows that the Debian version is older. Perhaps it'd be useful if you could include the fix above in a newer version of the sid packages?
