Segfault in 2.1.1 from RSpec expect_any_instance_of
Description
The following spec causes a segfault for me in ruby 2.1.1 on OS X 10.9.2:
class A def a 'a' end end class B def b 'b' end end describe 'segfault' do it 'should make unused recorders' do expect_any_instance_of(A).to receive(:a) expect_any_instance_of(B).to receive(:b) end it 'should crash ruby' do A.new.a B.new.b end end Some more info:
$ ruby -v ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin13.0] $ bundle exec gem list *** LOCAL GEMS *** bundler (1.6.0.rc) diff-lcs (1.2.5) rspec (3.0.0.beta2) rspec-core (3.0.0.beta2) rspec-expectations (3.0.0.beta2) rspec-mocks (3.0.0.beta2) rspec-support (3.0.0.beta2) I've also attached the crash report generated by OS X. Let me know if you need some more info. Sorry if this is a duplicate, I found some similar looking reports (#9309, #9461, #9315), but I don't really know enough to recognize if they are exactly the same issue.

Seems like stack overflow.
Could you try with the trunk?

Set the category to "doc" by mistake.

Sorry I missed the notification about your message. I've retried this with trunk (ruby 2.2.0dev (2014-04-25 trunk 45720) [x86_64-darwin13]) and it just gives a SystemStackError, with message "stack level too deep" now, so it does seem like stack overflow. Does that indicate that the segfault is fixed in trunk, and there may be a different bug in RSpec causing the stack overflow in the first place?
