This crash occures from r108112, I got it with manual bisecting. Zoltán, Gábor, could you check this annoying regression?

You can easily reproduce it with: $ Tools/Scripts/old-run-webkit-tests --iterations 1000 sputnik/Conformance/15_Native_Objects/15.1_The_Global_Object/15.1.3/15.1.3.2_decodeURIComponent/S15.1.3.2_A1.2_T2.html --exit-after-n-crashes 1

I skipped it to make buildbot happier - http://trac.webkit.org/changeset/108342 (and make it able to catch new regression) But it seems to be a serious regression, because crashes are always serious. Is there any volunteer interested in fixing this new crash?

more tests crash because of this bug: - sputnik/Conformance/15_Native_Objects/15.1_The_Global_Object/15.1.3/15.1.3.2_decodeURIComponent/S15.1.3.2_A1.2_T1.html - sputnik/Conformance/15_Native_Objects/15.1_The_Global_Object/15.1.3/15.1.3.1_decodeURI/S15.1.3.1_A1.2_T1.html Is there a JSC expert volunteer to fix it? Or these crashes aren't bug, but feature? :)
