** Description changed:
+ [Impact]
+ Users of GNU R and GNU Octave in Ubuntu 20.04 found that certain operations
hang, never returning results.
+
+ [Test Case]
+ apt install r-base-core
+ Rscript -e "example(solve)"
+ apt install libopenblas-dev
+ Rscript -e "example(solve)"
+
+ Executing Rscript the first time should return results almost instantly.
+ Installing libopenblas-dev ensures that libopenblas0-pthread is installed.
+ If the bug is present, running Rscript the second time will hang.
+
+ Another test case, using Octave, can be found in #1870138
+
+ [Regression Potential]
+ This fix is already present in lapack for some time, see Debian bug #722252
+ In case of regression, users should be able to switch to alternate blas
variants.

openblas >= 0.3.7+ds-3 causes an autopkgtest regression in hypre on
armhf on Ubuntu infrastructure.
There was a major restructuring of the openblas packaging in Debian
version 0.3.7+ds-2 uploaded to experimental.

Running tests
running TEST_ams ... autopkgtest [17:08:06]: ERROR: timed out on command
I have tried to reproduce this error on a Debian porterbox (armhf chroot
on arm64 kernel) and on a Raspberry Pi 3 (armhf focal-proposed chroot on
focal arm64 kernel). The autopkgtests using binaries from the archive
are successful, and rebuilding the packages locally is fine too.
While investigating, I found the same tests are run while building the hypre
package.
I uploaded the hypre package to my PPA with the following change:

The builds across all architectures seemed to fail in the same way as the
autopkgtests on armhf.
TEST_ams would start, and eventually the build would time out.
see e.g. the build log for amd64:
https://launchpad.net/~ginggs/+archive/ubuntu/testing/+build/18567417/+files
/buildlog_ubuntu-focal-amd64.hypre_2.18.2-1~ppa2_BUILDING.txt.gz
Again, I was unable to reproduce this error locally on amd64 or armhf.
This regression prevents openblas, yade, eckit, sdpa, openmolcas and
bolt-lmm from migrating from -proposed.
