Encountered two errors using webpacker and Rails 6 alpha when compiling assets onto a Centos 7 system after upgrading concurrent-ruby to v 1.1.7.

OS: Linux Centos 7
Ruby: ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-linux]
Rails: 6-alpha
concurrent-ruby-ex and concurrent-ruby-edge not installed.

The first problem was NoMethodError: undefined method `+' for nil:NilClass. This error was solved (see below).

This was solved by adding an additional paths declaration to config/webpacker.yml

The next deploy, a segmentation fault error appeared:

The full backtrace is available if relevant. Reverting to 1.1.6 solved this issue.

We have other projects using Rails 6.0.3.2 and the asset pipeline that are not affected by upgrading to 1.1.7.

Thanks for the report but unfortunately there is nothing to go on. concurrent-ruby is not even in the backtrace. Please keep digging what is wrong.

Thank you for your answer. Before opening the issue, I had gone back and forth between concurrent-ruby 1.1.6 and 1.17 several times, and I was able to reproduce the error.

I took several steps to investigate: I used Rails 6.0.3.2 instead of 6 alpha; I forked concurrent-ruby and reverted #879; I changed several assets to force new compilation; and under all these circumstances I could not duplicate the problem. So it is difficult to say what the cause. So I shall have to apologize for the trouble.

Thanks. No problem at all. It's good that it was reported for others to find.
What did you do in the end, stayed on 1.1.6?
