I'm just adding my 'cent' to ruby 2.6 mass rebuild - Vim started to fail after
ruby-2.6 was introduced to rawhide, but it fails only on i686 and armv7hl:
The error looks like mistake in C programming, but I already tried to build current Vim
with old ruby in copr and the build passes, but it fails with new ruby. Did anyone
encounter such errors with new ruby?
