Skipped on Qt in http://trac.webkit.org/changeset/151105. Please unskip it with proper fix.

(In reply to comment #1) > Skipped on Qt in http://trac.webkit.org/changeset/151105. > Please unskip it with proper fix. After the skip now fast/js/cyclic-prototypes.html is crashing. The last test run befor these is fast/js/custom-constructors.html, maybe that test is responsible for the crashes.

fast/js/cyclic-proto.html is unskipped and fast/js/custom-constructors.html is skipped in http://trac.webkit.org/changeset/151171. It's hard to reproduce the crash on local environment, let see what happens on the bots.

Were the crashes reliable on the bots, or did the first one just start at r151020? If I remember right r151020 was the first revision that crashed locally. I had to re-run some times the tests to get a crash. Somehow the problem has a connection with fast/js/custom-constructors.html, because after skipping that test no more crashes occurred, as I saw.

I re-run the tests with 151020: ../run-in-xvfb.sh Tools/Scripts/run-webkit-tests --no-new-test-results --debug-rwt-logging --no-show-results --no-sample-on-timeout --results-directory layout-test-results --debug --webkit-test-runner --qt fast/js/custom-constructors.html fast/js/cyclic-proto.html --iteration=100 07:17:44.710 3295 worker/0 fast/js/custom-constructors.html output stderr lines: 07:17:44.710 3295 ERROR: Unabled to create LocalStorage database path 07:17:44.710 3295 /home/azbest/webkit/WebKit/Source/WebKit2/UIProcess/Storage/LocalStorageDatabaseTracker.cpp(146) : WTF::String WebKit::LocalStorageDatabaseTracker::databasePath(const WTF::String&) const 07:17:44.710 3295 ERROR: Icon database already has a path and is already open.

Were the crashes reliable on the bots, or did the first one just start at r151020? It seems you're right. I checked again r151021 and I got the crashes with WK2: ../run-in-xvfb.sh Tools/Scripts/run-webkit-tests --no-new-test-results --debug-rwt-logging --no-show-results --no-sample-on-timeout --results-directory layout-test-results --debug --webkit-test-runner --qt fast/js/custom-constructors.html fast/js/cyclic-proto.html Regressions: Unexpected crashes (2) fast/js/custom-constructors.html [ Crash ] fast/js/cyclic-proto.html [ Crash ] fast/js/custom-constructors.html is not always crashing, but that test causes to crash the next after it. Also I got sometimes *** glibc detected *** /home/azbest/webkit/WebKit/WebKitBuild/Debug/bin/WebKitTestRunner: malloc(): memory corruption (fast): 0x00000000021877e4 ***
