I byte-compile my
~/.emacs.d/init.el. It was done by Emacs 26.1 from Cygwin and I got error when load
emacs-nox 25.2 from Debian WSL:
error: Invalid byte opcode: op=183, ptr=2
Were new opcodes introduced into Emacs byte code starting from v26? For what purpose?
I have no issues to load byte compiled files between v22-v25...
