           Summary: Exceptions aren't caught in some cases
           Product: WebKit
           Version: 526+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Keywords: SquirrelFish, SquirrelFishBlocker
          Severity: Blocker
          Priority: P1
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: oliver at apple.com


This hideous URL results in bogus behaviour:
javascript:try {(valueThrower={valueOf:function(){throw "throw from valueOf"}},
function () { executedRHS = false; var result = 'PASS'; try { result =
++valueThrower; alert('FAIL: Did not throw exception') } catch (e) { if (result
!= 'PASS' && executedRHS) { alert('FAIL: "'+expr+'" threw exception, but
modified assignment target and executed RHS'); } else if (result != 'PASS') {
alert('FAIL: "'+expr+'" threw exception, but modified assignment target'); }
else if (executedRHS) { alert('FAIL: "'+expr+'" threw exception, but executed
right hand half of expression') } else { alert('PASS: handled correctly') } }
})()}catch(e){alert("Shouldn't receive: "+e);}
