class variable is not being handled correctly
|ruby -v:||ruby 2.0.0p353 (2013-11-22 revision 43784) [x86_64-linux]||Backport:||1.9.3: UNKNOWN, 2.0.0: UNKNOWN|
I was doing an experiment after discussing with Charles Nutter whether the memoize pattern (@v ||= value_processing) was atomic in MRI and found what seems to be a curious bug in MRI implementation:
Shouldn't the output be 1, 101, 102, 102 instead of 1, 1, 102, 102?
Also, should I post the code and output here or is it ok to just link to it? Also, if I were to paste the code here, how am I supposed to format Ruby code in this Redmine?
