Hi Hans,
Someone posted on the tlbuild mailing list that LuaMetaTeX segfaults
whenever making the ConTeXt format on OpenBSD. I'm all out of ideas for
how to fix this, so hopefully you have some suggestions? The original
thread started at
https://tug.org/pipermail/tlbuild/2025q1/005651.html
Thanks,
-- Max
