Bug #14653: Bootsnap gets segmentation fault

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 2.6.0dev (2018-03-29 trunk 63037) [x86_64-linux]
• Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN

[yahonda (Yasuo Honda)]

Steps to reproduce

$ rbenv install 2.6.0-dev
$ rbenv global 2.6.0-dev
$ gem install bundler
$ git clone https://github.com/Shopify/bootsnap
$ cd bootsnap
$ bundle
$ rake
$ bundle exec bin/testunit

Expected result

bundle exec bin/testunit should pass. Ruby 2.5.1 passes all tests.

Actual result

$ ruby -v
ruby 2.6.0dev (2018-03-29 trunk 63037) [x86_64-linux]
$ rake

Related

I have reported these issues at Rails and Bootsnap and disucssed it should be filed to bugs.ruby-lang.org.
https://github.com/rails/rails/issues/32339
https://github.com/Shopify/bootsnap/issues/148

Also, I have found this report. It looks like similar with mine but not sure it is duplicate.
https://bugs.ruby-lang.org/issues/14596

[wanabe (_ wanabe)]

I guess it is fixed at [Bug #14553] r63040.
(And it also needs [Bug #14660] r63103 to pass all tests, but although it is not directly related to this issue.)

Would you please retry with latest trunk ruby?

An Execution result of my environment is here.
