var exeception

[Jakob Kummerow, 2011/12/13 13:04:37]

Done. Copy-paste-error.

+try {
+  setx();
+  assertUnreachable();
+} catch (ex) {
+  assertTrue(typeof(ex) == 'string');
+  exception = true;
+}
+assertTrue(exception);

[Rico, 2011/12/13 11:28:39]

we don't really need this: exception=false => we should have hit
assertUnreachable

[Jakob Kummerow, 2011/12/13 13:04:37]

Right. Done.

+
+// This used to trigger a crash because of an unhandled stack overflow.
+function sety() {
+  sety(typeof new Uint16Array(1) === 'object');
+}
+
+var exception = false;

[Rico, 2011/12/13 11:28:39]

not var

[Jakob Kummerow, 2011/12/13 13:04:37]

Done.

+try {
+  sety();
+  assertUnreachable();
+} catch (ex) {
+  assertTrue(ex instanceof RangeError);
+  exception = true;
+}
+assertTrue(exception);
