Thanks for looking into this.

Not really, I stick with pdftex and xetex for my CWEB stuff. :o)

However, I ran 'Build -disable-all-pkgs --enable-web2c' from scratch and 
apart from the three segfaults with 'luatex [-ini]' (simple 'luatex' 
still bombs) I do not find any unusual compiler warnings in build.log.


I guess it's up to Luigi to deal with this issue.

Hmm, still fails on x86_64 (but not i38) on svn 73311
https://github.com/TeX-Live/texlive-source/actions/runs/12614970192/job/35154476160

Strange.

Thanks for looking into this. I just returned from a skiing holiday and
working through the backlog, that was on my list.

Best regards
