Good to have this follow-up, indeed ... (For a fix in htslib either a new LP bug is needed or htslib needs to be added to this one as 'affecting package'.)
So I did some investigations and found that the "Remove compressBound assertions." merge request #1258 got upstream accepted with htslib v1.13: $ git log --oneline --grep "Remove compressBound assertions" 515f6df Remove compressBound assertions. (PR #1258) $ git tag --contains 515f6df 1.13 1.14 1.15 1.15.1 But we already have v1.13 in the latest Ubuntu releases: $ rmadison -a source htslib htslib | 0.2.0~rc3-1 | trusty/universe | source htslib | 1.2.1-2ubuntu1 | xenial/universe | source htslib | 1.7-2 | bionic/universe | source htslib | 1.10.2-3 | focal/universe | source htslib | 1.13+ds-2 | impish/universe | source htslib | 1.13+ds-2build1 | jammy/universe | source htslib | 1.13+ds-2build1 | kinetic/universe | source So PR #1258 is already included in the htslib version of kinetic/22.10, jammy/22.04 and impish/21.10 (and I even double-checked the code). It's not included in focals/20.04 v1.10.x - and it looks like the PR cannot be simply applied to v1.10, since the code in v1.10 is too different - which will be a problem. Since the regression was found in jammy's zlib 1.2.11.dfsg-2ubuntu8 in combination with 1.13+ds-2build1 - I am unsure if PR #1258 is really the fix or if there something else needed on top?
