From: usa@... Date: 2019-08-26T15:10:40+00:00 Subject: [ruby-core:94570] [Ruby master Bug#15887] Process.argv0 can return bad values in Ruby 2.5 Issue #15887 has been updated by usa (Usaku NAKAMURA). Backport changed from 2.4: DONTNEED, 2.5: REQUIRED, 2.6: DONE to 2.4: DONTNEED, 2.5: DONE, 2.6: DONE ruby_2_5 r67761 merged revision(s) ea42423908ed055f9039b1dce6e9a232a3b2dd90. ---------------------------------------- Bug #15887: Process.argv0 can return bad values in Ruby 2.5 https://bugs.ruby-lang.org/issues/15887#change-81027 * Author: joeym (Joey Marianer) * Status: Closed * Priority: Normal * Assignee: * Target version: * ruby -v: ruby 2.5.5p157 (2019-03-15 revision 67260) [x86_64-darwin18] * Backport: 2.4: DONTNEED, 2.5: DONE, 2.6: DONE ---------------------------------------- MacOS 10.14.5 on a clean (source, using ruby-install) installation of Ruby 2.5.5 ``` $ ruby --version ruby 2.5.5p157 (2019-03-15 revision 67260) [x86_64-darwin18] $ gem install vault vcr virtus webmock webrick $ echo Process.argv0 | irb ``` ...sometimes returns `{}`, sometimes some other nonsense and sometimes segfaults, but never (or rarely enough that I haven't seen it) returns a string ending in `bin/irb` as expected. Unfortunately the bug only manifests when certain gems are installed; the set I included above is one possible set of gems that triggers the bug; I don't know what's special about it. -- https://bugs.ruby-lang.org/ Unsubscribe:
