Well, I dont really know, but maybe having symbols in modules trigger a
crash in native compilation emacs? Wouldn't then removing the symbols
from the module remove the crash?

I attach a gdb bt below, but I really didnt do anything except load the
module, the crash happens immediately.

The crash does happen inside the module, but for me, only in native
compilation emacs.
