Could you show small code to reproduce it and/or show local variables with a debugger?

Hi,

I have the same problem, exactly the same Ruby version and revision. I can supply a crash report or 3 if you require, here is some code that causes it:

require 'nenv'
require 'dotenv/load'
require 'sequel'
require 'pry-byebug'

unless defined? DB
  DB = Sequel.connect(Nenv.database_url) # <-- this line
end

ruby/2.5.0/gems/sequel-5.8.0/lib/sequel/adapters/postgres.rb:146: [BUG] Segmentation fault at 0x0000000000000000
ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin13]

I was running ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-darwin13] with the same code, no problems.

Let me know if you need any more.

Regards,
iain

I wanted to use ruby v2.5.1 instead v2.5.0
But I got this error.
With ruby v2.5.0, my rails project works great without any error.

I was using Rails v5.2.1 on macbook pro macos High Sierra 10.13.6 with Postgres.app v2.1.4

I avoided this problem by reinstalling vendor/bundle. My OS is macOS High Sierra.

I guess vendor/bundle/ruby/2.5.0/gems/pg-0.21.0/lib/pg_ext.bundle is inconsistent.

After I overwrote with the pg_ext.bundle made in ruby-2.5.0, it reproduced.

Do you mean they are binary incompatible?
Only the difference between 2.5.0 and 2.5.1 in the headers seems [Bug #14425].

[masutaka (Takashi Masuda)]

Yes. I'm not sure but they are binary incompatible.
