OK, I excluded ppc64el.

I decided to restrict the package to amd64 only since this is the
architecture which is most probably used and tested by upstream.

BTW, the autopkgtest for riscv64 does not have "Segmentation fault"
but

  
https://ci.debian.net/data/autopkgtest/unstable/riscv64/w/wtdbg2/27987776/log.gz

has:

This does not make the testing itself better, but I wanted to mention
this in case the debci setup needs to adjust some timeouts.

Kind regards
Andreas.

Bug#1025249: wtdbg2: flaky autopkgtest: Segmentation fault

2022-12-01 Thread Paul Gevers

Source: wtdbg2
Version: 2.5-7
Severity: serious
User: debian...@lists.debian.org
Usertags: flaky

Dear maintainer(s),

I looked at the results of the autopkgtest of your package because it 
was blocking glibc. I noticed that it regularly fails (particularly on 
ppc64el, but not exclusively there).


Because the unstable-to-testing migration software now blocks on
regressions in testing, flaky tests, i.e. tests that flip between
passing and failing without changes to the list of installed packages,
are causing people unrelated to your package to spend time on these
tests.

Don't hesitate to reach out if you need help and some more information
from our infrastructure.

Paul
