Package: libmumps-ptscotch-dev
Version: 5.1.2-4+b2
Severity: important
Dear Maintainers,
The library SEGFAULT on the buster(stable) package libmumps-ptscotch-dev
5.1.2-4+b2 for the amd64 architecture.
I used some well-known medium-sized sparse matrix as tests.
This problem could be fixed on buster by a simple recompilation of the package:
apt-get source mumps
cd mumps-5.1.2
dpkg-buildpackage -us -uc -sa -j1
dpkg -i libmumps-5.1.2-4_amd64.deb libmumps-dev-4_amd64.deb
libmumps-scotch-5.1.2-4_amd64.deb libmumps-scotch-dev-4_amd64.deb
libmumps-ptscotch-5.1.2-4_amd64.deb libmumps-ptscotch-dev-4_amd64.deb
On the bullseye (testing) distrib, there is no problem at all.
So, perhaps a binanry dependency has change for mumps on buster(stable),
and (I dont known why) the package has not been yet recompiled ?
Best wishes,
Pierre

The test suite (examples) for MUMPS 5.1.2 is passing in chroot for
buster.
Copying and adapting debian/tests from mumps 5.3.1 in unstable to run on
buster with mumps 5.1.2, all tests run and pass, including
multiple_arithmetics_example.
We've got no confirmation that there is a bug in MUMPS in stable
(buster). Since tests pass successfully, we have to conclude the
reported problem was a transient problem on the host system.
I ran these buster tests against libopenblas-dev and did not check other
BLAS implementations.
If you do continue to experience the problem then please report which
BLAS or LAPACK implementation you have installed, and please provide a
test case.
Since MUMPS tests are passing on buster, I'm closing this bug now.
Drew
