Package: clustalo Version: 1.2.4-6 Hi, as initially found and discussed on Launchpad/Ubuntu [1] there is a segfault of clustalo on s390x. So far it didn't hit you on your s390x builds [2] but it seems pretty reliable for us already and on a rebuild in Debian unstable I've hit it as well. It is triggered by the new self-test after build in 1.2.4-6.
The underlying root cause was identified in [3] which I also reported to upstream and the Debian Med Team as mail. We now have three options: - wait for upstreams stance on the suggested change - switch optimization to -O0 on s390x which avoids the issue for now - apply the suggested patch without upstream commenting on it This is up to you to decide what you prefer and I last week already opened an MR for it [4].
