Recently our common_test suites started to fail in our (gitlab-runner)
CI environment with errors like this:

        {dir_SUITE,init_per_testcase,
            {{noproc,
                 {gen_event,call,
                     [cth_readable_logger,cth_readable_failonly,

             [{gen_event,call1,3,[{file,"gen_event.erl"},{line,207}]},
              {cthr,pal,4,

"/usr/src/rebar3-src/_build/default/lib/cth_readable/src/cthr.erl"},
                   {line,74}]},

As far as I understand the gitlab CI environment and our setup, the CI
job fetches the erlang:19 Docker image:

Using docker image
sha256:2ea95f0c3147e50b79b4fcd28c955c80c2e57eb20fb8ff61bb8ed1873d0b6957
for erlang:19

and executes our test suite in that image. Our code did not change,
but it looks like the image did change, at least at the latest
successful test I see this in the logs:

Using docker image
sha256:e36b5300c4cf2f504f0222ea66bbf81fb2e514ad88cb93f111b5e85e7893b99a
for erlang:19

Do you know what could cause this problem?
