Hi Michal,
The error indicates some bad whatsit subtype being used. Can you check if any of the packages that gets loaded here, does some numeric whatsit node allocation? The late literal has its own whatsid subtype (I might collapse it at some time into the regular one as that makes more sense.) which makes e.g. save, restore, user ones move up in the subtype number range.
(I don't want to waste more time than i already did chasing something that is possibly outside the engines scope, so best check this first before I look deeper down the code.)
Hi Hans, thanks for the hint, I didn't dare to look closer, because I didn't really understand the LuaTeX commit and frankly don't have a lot of time for TeX these days. But the fact that whatsit subtypes got renumbered of course means that something like this is not going to work well: append:node(node.new(8, 30)) -- q Hastily I put together a patch for minim. Now it is up to Esger Renkema (CC'd) to solve the issue. https://gitlab.com/renkema/minim/-/merge_requests/7 Thanks again and sorry for the noise. Michal
