I am currently finishing the first release of my Ruby-GTK3 schematics tool (http://ssalewski.de/PetEd.html.en.) Unfortunately yesterday, after some trivial cleanup in the source code I got permanent Garbage-Collector related crashes with Ruby 2.1. Luckily switching back to Ruby 2.0 fixed it. So I have the strong feeling that there is something wrong with Ruby 2.1 interpreter -- my code is pure Ruby, no own C extensions. Of course reporting that bug to upstream is difficult, 6k lines of Ruby code, not cleaned up well yet. Ruby 2.0 is ok for me (as long as I get no new crashes), but of course it would be great to getting 2.2 support soon. Reproducible: Couldn't Reproduce
I've now added the ruby22 target to dev-ruby/ruby-gnome2 and its dependencies.
Thank you very much.
