Issue #14343 has been updated by vo.x (Vit Ondruch).


Ok, this is the patch I'm going to use for Fedora:

https://src.fedoraproject.org/rpms/ruby/blob/master/f/ruby-2.5.0-parse.y-assignable_error.patch

It fixed the issues with webmock and ffi documentation according to my tests.

Anyway, I would appreciate if Ruby was not needed to apply patches to ruby tarball.
