After looking at JSTests/test262.yaml in more details, I saw that this program was marked :fail, so visibly it was expected that the test would fail, and the testing harness is now complaining that it no longer does. This assumption was last changed in https://bugs.webkit.org/show_bug.cgi?id=177859. Interestingly, increasing the number of iterations to 100000 makes the test fail with stack overflow. This looks possibly related to https://bugs.webkit.org/show_bug.cgi?id=176703. 1364269 3 ryanhaddad 2017-10-25 10:15:39 -0700 The bot has been red for days due to this issue. Should we go ahead and mark the test as passing? 1364300 4 ryanhaddad 2017-10-25 10:42:54 -0700 I confirmed with Robin that we should mark the test as passing.
