After r118868 the Qt Lion Intel Release bot exits early because of too many crashes: http://build.webkit.sed.hu/builders/Qt%20Lion%20Intel%20Release/builds/5189 (r118867 works fine apart from 5 crashes and 14 failures: http://build.webkit.sed.hu/results/Qt%20Lion%20Intel%20Release/r118867%20%285199%29/results.html ) Could you check what happened? Unfortunately the bot doesn't provide useful backtraces and I don't have Qt Lion build to try to reproduce this bug and I don't have any JSC/GC experiences to debug it myself. So it would be great if there is any Qt volunteer with Qt Lion build for fixing this bug.
It isn't Qt specific bug, because there are crashes on Apple Lion bot too: http://build.webkit.org/results/Lion%20Release%20%28Tests%29/r118868%20%288774%29/results.html
