[ruby-core:67983] [ruby-trunk - Bug #10822] make-snapshot breaks during download of bundled gems

Issue #10822 has been updated by Vit Ondruch.


I fixed the Fedora's side. If you want to reproduce, the original operating system_rb is still available here:

This is due to Ruby picking up rbconfig.rb from the current checkout, since $(RUNRUBY) adds the current directory on the load path [1]. I don't think this is right in this case.

You can reproduce this issue with Fedora's operating_system.rb [2].
