          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Keywords: NeedsRadar
          Severity: Normal
          Priority: P2

this.__defineSetter__("d", function h(){ throw ""});
function g() {
    d = 0;
}
for (;;) try { g() } catch(e){ }

Crashes on an assertion due to us not catching the exception properly.  some print debugging shows that we continue executing after d=0
