I would appreciate if you could show me a sample code to reproduce this crash.
Environment is: ruby 2.5.3, rails 5.2, ubuntu 18.0.4
In a new rails project, just add below statement in Gemfile:
gem "numo-narray"
gem "numo-linalg"
Than run: rails s
It will crash and occur core dump like above
(* Windows environment is no problem, CentOS 7 also has same problem)
I got same crash, but this is due to a problem in ruby 2.5.x.: https://bugs.ruby-lang.org/issues/15200
Possible solutions:
- Use ruby 2.6.
- Apply patch to numo-linalg: 87732ca
- Unuse 'bootsnap' option which is set in config/boot.rb in your rails project.
