It's OK, I'm able to reproduce it.

TEST CASE
---------
void bug4938()
{
    try
    {
        return 0;
    }
    catch (Undefined4938 ee)
    {
        return 3;
    }
}
-----------

PATCH
statement.c, line 4132.
-----------
int TryCatchStatement::blockExit()
{
    assert(body);
    int result = body->blockExit();

    int catchresult = 0;
    for (size_t i = 0; i < catches->dim; i++)
    {
        Catch *c = (Catch *)catches->data[i];
+        if (c->type == Type::terror)
+            continue;
        catchresult |= c->blockExit();

        /* If we're catching Object, then there is no throwing
         */
+       assert(c->type->toBasetype()->isClassHandle());
        Identifier *id = c->type->toBasetype()->isClassHandle()->ident;
