crash 1.9.3

Added by mrbrdo (Jan Berdajs) over 12 years ago. Updated over 11 years ago.

Closed
Target version:
-
ruby -v:
ruby 1.9.3p234 (2012-06-02 revision 35866) [x86_64-darwin11.4.0]
Backport:
[ruby-core:45441]

Description

I was playing around and I got the 1.9.3 interpreter to crash.
Code: https://gist.github.com/2880210
Don't bother too much with the code I was just playing around. What I am doing there shouldn't work anyway, but it shouldn't crash the interpreter either :) At least I guess.
Run with rspec filename.rb. The crash is related to method_missing and I guess it goes into an infinite circular thingy. Not really sure if something like this is supposed to not error out like this anyway, but I thought I should let you guys know.

I cannot reproduce this crash with ruby 1.9.3p125 or ruby trunk r35913.

Can you show the output of your crash?

=begin
I have reproduced it and created a minimal test case (without rspec):

class TestClass
def self.tdef name, &tdef_body
define_method name do
self.class.send(:define_method, :method_missing) do |meth, *args|
crash_in_infinite_loop(meth, *args)
end

    instance_eval(&tdef_body)
  end
end

tdef :hello do
  call_method_missing
end

end

TestClass.new.hello

=end

Attaching my crash report for my test case (in case it's not the same issue as with your test case). You said you were not able to reproduce it, did you run it with rspec instead of ruby?
Anyway if it's the same problem, your code is more appropriate to test anyway.

Running this code in 1.9.3p0 I don't get a crash, but a simple "stack level too deep (SystemStackError)".

Close because this cannot be reproduced in ruby_1_9_3 branch.
