bug#47318: 26.3; Modules on Emacs 26.3 broken?

[Sanel Zukan]

Hi guys,

I'm getting this [1] error from freshly compiled Emacs 26.3 and
vterm-module.

Also, emacs-eject [2] and very simple module [3] fails on 26.3 with the
similar error. However, they are working fine on 27.1.

Any idea what could go wrong? I also tried to run bare Emacs with
'emacs -Q'. In the all cases, Emacs is compiled with modules support.

Best regards,
Sanel
