Package: release.debian.org
Severity: normal
Tags: bullseye
User: release.debian@packages.debian.org
Usertags: pu
X-Debbugs-Cc: nil...@debian.org
[ Reason ]
The package segfauls to !amd64 and !i386 architectures. The version in
bullseye does not have autopkgtests, when we added those and uploaded
_after_ the bullseye release, tests were segfaulting on arm64, ppc64el
and armhf. Note that there has been no new upstream release, just test
addition with a few cosmetics.
Unfortunantely, the failing logs of the 0.3.4-4 version have disappeared
from here[1]
But, trying on a arm64 porter box confirms the experience.
% ./segemehl -x index.idx -d seq1.fa
[SEGEMEHL] Mon Sep 6 18:29:55 2021: reading database sequences.
zsh: segmentation fault ./segemehl -x index.idx -d seq1.fa
% ./segemehl -i index.idx -d seq1.fa -q myseq.fa > mymap.sam
[SEGEMEHL] Mon Sep 6 18:44:08 2021: reading queries in 'myseq.fa'.
...this keeps running forever
This has been fixed in unstable with the relevant patch, and upload[2]
0.3.4-5 and it migrated to testing after everything passes

[2]:
https://tracker.debian.org/news/1251311/accepted-segemehl-034-5-source-into-unstable/
Since I noticed and fixed it before any bug was filed, there does not
exist a corresponding RC bug in the database. Let me know if I should
file one and process BTS commands on that.
[ Impact ]
Users will find a broken segfaulting package on !amd64 and !i386
machines
[ Tests ]
Autopkgtests have been added. I've manually run them on porter boxes,
and it looks good (as it should)
The revision in unstable also has tests passing
https://ci.debian.net/data/autopkgtest/unstable/arm64/s/segemehl/14839955/log.gz
[ Risks ]
Being a leaf package with a not-very-high popcon, risk is pretty low
