Subject: [ruby-core:37066] [Ruby 1.9 - Bug #4651] Bus Error using continuation on x86_64-darwin11.0.0 (Lion)


Issue #4651 has been updated by Levin Alexander.

File config.log.xcode4.0.2.txt added

I downgraded to XCode 4.0.2 (4A2002a) and recompiled ruby with rvm. This makes the problem go away. (both for 1.9.2p180 and p274)

$ ruby --version
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin10.7.0]
$ ruby cc.rb 
cc.rb:3:in `<main>': undefined method `call' for nil:NilClass (NoMethodError)
# no crash :)

attached is the config.log from this compilation for comparison.

=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.
