recompile few packages manually (ruby, libxml2) but it didn't help. Any help would be appreciated
Created attachment 654834 [details] Segmentation fault log
I downgraded 3 packages (they depend on each other) able to run it again: dev-libs/libxml2-2.9.9-r3 dev-libs/libxslt-1.1.33-r1 dev-ruby/nokogiri-1.10.4
I narrowed down the issue. It is dev-libs/libxml2-2.9.10 version cases the crash
