[Debian-pan-maintainers] Bug#1032902: Numba issues for genx for other architectures than amd64 and ppc64el (Was: genx won't start: TypeError: Pen(): arguments did not match any overloaded call)

[Andreas Tille]

Hi,

I've found genx in the "Cleaner view"[1] due to missing builds[2].
It turns out that for instance for arm64[3] the build fails with

   tests/test_numba_equivalency.py Fatal Python error: Segmentation fault

For armel[4] (and armhf) we get

   dh_auto_test -a -O--buildsystem=pybuild
I: pybuild base:240: cd /<<PKGBUILDDIR>>/.pybuild/cpython3_3.11/build; python3.11 -m pytest tests
Fatal Python error: Aborted

Current thread 0xf7a30020 (most recent call first):
  File "/usr/lib/python3/dist-packages/llvmlite/binding/ffi.py", line 151 in __call__
  File "/usr/lib/python3/dist-packages/llvmlite/binding/executionengine.py", line 92 in finalize_object

  ...

For i386[5]

I: pybuild base:240: cd /<<PKGBUILDDIR>>/.pybuild/cpython3_3.11/build; python3.11 -m pytest tests

   ...


and we have other errors for other architectures which all contain
the string "numba".  IMHO this is a mess we can hardly fix in hard
freeze.  I see only two chances:

   1. Restrict the architectures to amd64 and ppc64el (which are
      the only ones where the build succeeds or
   2. Remove the package from testing for the moment.  The only
      rdepends is currently pan-grazing-incidence which will be
      lowered to suggests once we re-render debian-pan metapackages.

What do you think?

Kind regards
    Andreas.
