Check https://bugs.webkit.org/show_bug.cgi?id=77736#c21 for details. It is P1-critical bug, because crashes are always serious problems.

(In reply to comment #0) > Check https://bugs.webkit.org/show_bug.cgi?id=77736#c21 for details. > It is P1-critical bug, because crashes are always serious problems. It is true on 32 bit relase mode. I tried a 64 bit debug build (because 32 bit debug build is impossible) and now an other test crashes: svg/zoom/page/zoom-coords-viewattr-01-b.svg when I run svg/zoom tests. It passes if I run only this test. Here is the crash log: ASSERTION FAILED: !result /home/oszi/WebKit/Source/JavaScriptCore/wtf/ThreadingPthreads.cpp(282) : void WTF::Mutex::lock() 1 0x7fd7ffcdebc5

Why did you removed bug77736 from the block list without any comment? This is a regression caused by bug77736, so this bug blocks 77736.

Comment 3 2012-02-07 13:23:32 PST

I've seen a similar assertion failure in a recent bug I've worked on and it was a dangling pointer left between test cases (this is why it worked fine outside the test scope)... not sure if this is the case for WK1, but checking the life cycle of whoever is involved here might be helpful (and the return of WTF::Mutex::lock() as it may indicate the object has been deleted).

Comment 4 2012-02-07 14:05:18 PST

I tried to skip this test locally, but then the following tests started to crash. Skipping the test before it didn't hide the crash, but skipping two tests before it "solved" the crash: svg/zoom/page/zoom-background-images.html svg/zoom/page/zoom-coords-viewattr-01-b.svg So I skipped them to make the bot green to be able to catch new regressions - http://trac.webkit.org/changeset/106989 Please unskip them with the proper fix.

(In reply to comment #2) > Why did you removed bug77736 from the block list without any comment? > This is a regression caused by bug77736, so this bug blocks 77736. Did I do this? I hope not. The stack traces are obvious, speculative fix coming.
