Hello Everyone.

I recently forked https://github.com/813gan/emacspy.
It's dynamic module that allows interacting with python using libpython (no subprocess).
My intention is to allow Emacs modes to use python modules including bindings of external libraries.

I'm facing problems with --module-assertions.
With mentioned flag enabled emacs is printing
"Emacs module assertion: Emacs value not found in 57 values of 1 environments"
and dumps core.

Crash is reproducible with Makefile target test_module_assertions (https://github.com/813gan/emacspy/blob/f61275c6d3adec7947d292b8a9df25551e40c869/Makefile#L68)

I have absolutely no idea what is going on there. Only thing i discovered is that commenting line
https://github.com/813gan/emacspy/blob/f61275c6d3adec7947d292b8a9df25551e40c869/emacspy.pyx#L140
prevents crash. It's obviously not a solution.

Otherwise module appears to work;
Despite that i don't want to ship it as i assume emacs have good reason to crash.

I would appreciate any help. If you need more information, please contact me.

Happy Hacking!
