But it should block 2.2 release, because it would be a shame if we would release QtWebKit 2.2 with this annoying JSC bug. r90673 is not present in QtWebKit-2.2 and the mac-buildbot for 2.2 has been unstable for a while... Is there a correlation between the failures from there and this bug?

Maybe r90673 is absolutely innocent. I noticed crashes from this revision. But debugging without crash log and without QtWebKit build on Mac is absolutely impossible. Somebody who has QtWebKit build on a Mac should debug this bug. I don't think if the bot is unstable, but there is a serious JSC bug in QtWebKit on Mac. But I can't confirm it without a local build. 464890 7 ademar 2011-09-09 10:40:50 -0700 Since we're not sure if this bug indeed affects qtwebkit-2.2, I'm removing it from the blockers list. If we get confirmation, we'll add it back. BTW, the build passed just now and the 2.2 mac bot is now green. 464899 8 ossy 2011-09-09 10:50:36 -0700 (In reply to comment #7) > Since we're not sure if this bug indeed affects qtwebkit-2.2, I'm removing it from the blockers list.

I think removing this bug from blocker list and/or releasing QtWebKit 2.2 without checking what cause random crashes on Mac is absolutely non-sense ... PS. I'm sure that the Mac bot will be red for the next build. 464921 9 ademar 2011-09-09 11:14:05 -0700 (In reply to comment #8) > (In reply to comment #7) > > Since we're not sure if this bug indeed affects qtwebkit-2.2, I'm removing it from the blockers list.

I think removing this bug from blocker list and/or releasing QtWebKit 2.2 without checking what cause random crashes on Mac is absolutely non-sense ... We're about to release a qtwebkit-2.2 RC and this problem (or non-problem) has always been there. If that's indeed a problem, we'll catch it somewhere down the road and add the fix to the release branch. But keeping a bug blocking the release without anyone working on a fix and without even knowing if it's indeed a problem won't benefit anybody. We'll never release 2.2 if we want it to be perfect. > > PS. I'm sure that the Mac bot will be red for the next build. I'm sure too, and it has been like this for ages. I'm not saying it's a good thing, I'm just saying that I don't know what's causing it and I don't see resources being allocated to fix it. 466169 10 ossy 2011-09-13 00:19:36 -0700 js1_5/Regress/regress-152646.js and js1_5/Regress/regress-192414.js started to fail again after http://trac.webkit.org/changeset/95016 466170 11 ossy 2011-09-13 00:21:58 -0700 Change the name of the bug, because nobody can confirm if it is a regression or not, because nobody maintains QtWebKit on Mac now. :( 737455 12 ossy 2012-10-08 23:32:21 -0700 Nobody runs layout tests on Qt Mac, nobody knows if it is valid bug or not, so we can simple close it as wontfix.
