There are (at least) two issues why the tests fail in Impish right now.
It blocks xtensor itself, but also src:xtensor-blas.
The test fails on all architectures, but for different reasons.
The last good test was more than two years ago.
s390x / arm64 / i386 fail on bad-package.
- xtensor-dev became a transitional and is available on all arch.
- But the actual dependency libxtensor-dev only exists on a few
libxtensor-dev | 0.22.0-5 | impish-proposed | amd64, armhf, ppc64el, riscv64
- That explains the badpkg issue, and I guess we can just reset it
instead of spending too much time fixing the package.
- TODO test reset on those architectures
- Furthermore amd64 / ppc64 tests fail while armhf works.
https://autopkgtest.ubuntu.com/packages/x/xtensor/impish/amd64
- In debici this passes on amd64/arm64/armel/armhf/ppc64 but fails i386/s390x.
https://ci.debian.net/packages/x/xtensor/
- It appears to be a build error at first, but it really is an OOM (log below).
- The problem that this isn't just "big packages and being ok" I tried with 3G/4G/8G
memory. 4G still fails, 8G works so it is not an infinite-memory bug.
- TODO mark as big package once 8G is confirmed
The test also has some control about its concurrency, but I tried to reduce it to -j 1 and it still fails with an OOM. Even 4GB are not enough with nproc=1.
So 8G seems to be the minimum for this test.

The test also has some control about its concurrency, but I tried to reduce it to -j 1 and it still fails with an OOM. But then it works with 3G which is an improvement.
TODO: submit to Debian to reduce the nproc in this test case.
