Unfortunately can't post a link but the error is here in the eval of
the api code

S.prototype.ev=function(a){return new M(a.x+this.Ve.width,a.y
+this.Ve.height)};

Here is the function called.  Will do some try / catch blocks as well.

    function initialize()
    {
      map = new GMap2(document.getElementById("map_canvas"));
      map.setCenter(new GLatLng(34, 0), 15);
      geocoder = new GClientGeocoder();
      document.forms[0].q.value = QueryString("postalCode");
      showLocation();
    }

    function addAddressToMap(response)
    {
      map.clearOverlays();
      if (!response || response.Status.code != 200)
      {
        alert("Sorry, we were unable to find that address");
      }
      else
      {
        place = response.Placemark[0];
        point = new GLatLng(place.Point.coordinates[1],
place.Point.coordinates[0]);
        map.addControl(new GLargeMapControl());
        var mapControl = new GMapTypeControl();
        map.addControl(mapControl);
        map.addControl(new GScaleControl());
        map.addControl(new GOverviewMapControl());
        geocoder.getLatLng(     document.forms[0].q.value,
function(point) {      if (!point)
{        alert(document.forms[0].q.value + " not found");      } else
{        map.setCenter(point, 15);        var marker = new
GMarker(point);        map.addOverlay(marker);      }    }  );
      }
    }

Sorry, not too pretty on cut and paste.
