Package: mpich2
Version: 1.4.1-4
Severity: important
Tags: patch
In a minimal unstable chroot, after installing mpich2 with
--no-install-recommends:
nighthawk:/tmp# mpirun /bin/true
Segmentation fault
nighthawk:/tmp# apt-get install --no-install-recommends openssh-client
[...]
nighthawk:/tmp# mpirun /bin/true
nighthawk:/tmp# echo $?
0
nighthawk:/tmp# mv /usr/bin/ssh{,_}
nighthawk:/tmp# mpirun /bin/true
Segmentation fault
nighthawk:/tmp#
This also makes mpi-default enabled packages on MPICH architectures
segfault in test suites, see e.g. (grep for "1.1.1.1" or "Segmentation
fault"):
https://buildd.debian.org/status/fetch.php?pkg=aces3&arch=mips&ver=3.0.6-5&stamp=1342693895
Not sure whether it would help the test suite, but this seems to be a
known bug (http://trac.mcs.anl.gov/projects/mpich2/ticket/1576) with a
known fix: http://trac.mcs.anl.gov/projects/mpich2/changeset/9543
I have not tested this patch.
