[Debian-med-packaging] Bug#1025249: wtdbg2: flaky autopkgtest: Segmentation fault

[Paul Gevers]

Source: wtdbg2
Version: 2.5-7
Severity: serious
User: debian-ci at 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
