Subject: [ruby-core:37067] [Ruby 1.9 - Bug #4651] Bus Error using continuation on x86_64-darwin11.0.0 (Lion)


Issue #4651 has been updated by Levin Alexander.


diffing both config.log files:

the segfaulting ruby (XCode 4.2) is compiled with:

  gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)
  i686-apple-darwin10-llvm-g++-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)

the working ruby (XCode 4.0) is compiled with:

  gcc version 4.2.1 (Apple Inc. build 5666) (dot 3)
  i686-apple-darwin10-g++-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)

=begin
The following code crashes with a Bus Error on Ruby 1.9.2-p136 and 1.9.2-p180 built for x86_64-darwin11.0.0 (Lion). The same code works on both of those versions of Ruby built for x86_64-darwin10.0.0 (Snow Leopard).

(({require 'continuation'}))

(({cc = callcc {|cc| cc }; cc.call if cc}))

This actual code appears in the yard gem on ((<line 38 of yard.rb|URL:https://github.com/lsegal/yard/blob/master/lib/yard.rb#L38>)).

I've attached the crash log. Please let me know if you need any other information from me to help debug this issue. Thank you very much. Ruby makes me happy.
