Happy New Year!
Seeing that the recent Github Actions report "Segmentation fault (core
dumped)", see
<https://github.com/TeX-Live/texlive-source/actions/runs/12590089294>, I
tried the usual test with the current TeX Live source tree.
Building seemed to go fine (haven't checked en detail), but after
copying the resulting 'luatex' executable to the 'bin/x86_64-linux'
directory, 'luatex common.tex' (from CWEB) crashes with the attached log
file and this console output. The resulting PDF file is perfectly fine,
but at the end the 'Segmentation fault' occurs:
This is LuaTeX, Version 1.20.0 (TeX Live 2025/dev)
system commands enabled.
