Description Rolf Bjarne Kvinge [MSFT] 2014-07-30 07:21:32 UTC
Created attachment 7531 [details]

Run attached test case.

The output in mono will be intermittent True/False, with True for every odd number:

#0 = False
#1 = True
#2 = False
#3 = True

The output for MS is False for #0, and True for the rest:

#0 = False
#1 = True
#2 = True
#3 = True

> mono --version
Mono JIT compiler version 3.6.1 ((no/9d8be3d Sun Jul 27 20:49:44 EDT 2014)

I also tried with the tip of mono-3.6.0-branch and mono-3.4.0-branch, and both fail the test case.
