Source: growlight
Version: 1.2.37-2
X-Debbugs-CC: debian...@lists.debian.org
Severity: serious
User: debian...@lists.debian.org
Usertags: regression timesout

Dear maintainer(s),

With a recent upload of growlight the autopkgtest of growlight fails in
testing when that autopkgtest is run with the binary packages of
growlight from unstable. It passes when run with only packages from
testing. In tabular form:

                       pass            fail
growlight              from testing    1.2.37-2
all others             from testing    from testing

I copied some of the output at the bottom of this report. The message is
repeated over and over again until autopkgtest timesout.

Currently this regression is blocking the migration to testing [1]. Can
you please investigate the situation and fix it?

Hi,

exciting results! i wrapped up a similar invocation and threw it
into my notcurses drone CI, and there i fail exactly as i do
within the debian CI (i.e. we never terminate, though we don't
soak the CPU).

https://drone.dsscaw.com:4443/dankamongmen/notcurses/10240/1/2

i ought now be able to resolve this quickly, as i finally seem
able to reproduce it locally =].

When the latest notcurses migrated to testing this week, the issue was
gone. So let’s close this bug properly, shall we?
