Bug #3722: segfault in rb_iterate (1.9.3, r29057)

• Status: Closed
• Assignee: -
• Target version: 1.9.3
• ruby -v: ruby 1.9.3dev (2010-08-19 trunk 29056) [x86_64-linux]

[Cezary (Cezary Baginski)]

=begin
Reproducible every time while running bundler + cucumber + rprofile on a private rails project
(hard to reduce).

The second attached contains a short gdb session using Ruby with -g3/-O0/-ggdb.

I know this isn't much, but let me know if there is anything else I can do to help out.

I started tearing everything apart and came up with this minimal case:

% ruby --version
ruby 1.9.3dev (2010-08-19 trunk 29056) [x86_64-linux]

% cat fail.rb
require 'profile'
class A
include Enumerable

def each
yield 1
end
end
A.new.any? { true }

% ruby fail.rb
fail.rb: [BUG] cfp consistency error - send
ruby 1.9.3dev (2010-08-19 trunk 29056) [x86_64-linux]
