Description
I noticed that when a RSpec subject is self-referential, it causes infinite recursion and SegFaults ruby.
Steps to Reproduce:¶
spec/test_spec.rb¶
require 'rspec'
describe "Infinite Block Recursion" do
subject { 1 }
describe "foo" do
subject { subject }
it "should not segfault" do
subject
end
end
end
Command¶
ruby -S rspec spec/test_spec.rb
Expected Results¶
stack level too deep
Actual results¶
SegFault
Backtrace¶
gdb `which ruby`
(gdb) r -S rspec spec/test_ruby.rb
Infinite Block Recursion
foo
Program received signal SIGSEGV, Segmentation fault.
