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

Bug #6550: crash 1.9.3

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.
