Crash on specific input

[calebegg]

I narrowed down the relevant input to this (as far as I can tell, nearly everything here is required for the crash to occur):

goog.provide("foo.Foo");
goog.scope(function() {
  /** @constructor @param {!foo.Bar} bar */ var Foo = function(bar) { };
  /** @const */ foo.Foo = Foo;
});
goog.provide("foo.Bar");
goog.scope(function() {
  /** @constructor */ var Bar = function() { };
  /** @const */ foo.Bar = Bar;
});

Here's the stack trace:

@rkirov the goog.module strikes again :-(

@calebegg thanks for the great repro!
