Can anyone else reproduce or not reproduce this issue?

Control: tag -1 - unreproducible

The buildds could reproduce the problem:

Control: severity -1 important
Control: retitle -1 libsendmail-milter-perl: intermittent FTBFSes: Segmentation fault (core dumped)

And after a giveback back by release team it built (same URL).

Setting the seveverity to important since this is "intermittent
only".

I was about to submit the bug report below, but that would be a duplicate.

Source: libsendmail-milter-perl
Version: 0.18-10
Severity: serious
User: debian-ci@lists.debian.org
Usertags: flaky

Dear maintainer(s),

I looked at the results of the autopkgtest of your package because it
showed up in the excuses for glibc. I noticed that it regularly fails.
On some architectures more than on others, but it seems to happen
everywhere.

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
