ie8 bug when module() inside it() throws and exception (thrown during inject() call)

This is a bug where my exception object is getting lost.  Here's the
result from a Karma trace:

    Running "autotest:jqlite" (autotest) task
    INFO [karma]: Karma v0.11.0 server started at http://localhost:9876/
    WARN [web-server]: 404: /favicon.ico
    INFO [IE 8.0.0 (Windows XP)]: Connected on socket hfE_1IJ4LeFwf6RJcVOe

    IE 8.0.0 (Windows XP) SCE CKCK: IE8 TypeError FAILED
            Expected function to throw CKCK: foo , but it threw Object doesn't support this property or method
    IE 8.0.0 (Windows XP): Executed 1 of 2225 (1 FAILED) (skipped 2224) ERROR (7.738 secs / 0.031 secs)

I don't see the real exception but get a TypeError.  There is only one
stack frame between when the exception object is the one I want and the
one where it's been replaced by TypeError.  No code executes between
those two frames afaik from looking at the IE8 debugger.

In the inject() call:

      if (!injector) {
        injector = currentSpec.$injector = angular.injector(modules);
      }

the exception is thrown in "injector = currentSpec.$injector = angular.injector(modules);"

making injector undefined.  The caller frame is the anonymous function
in the expect() line:

    expect(function() { inject(angular.nop); }).toThrow('CKCK: foo');

When control reaches that frame through, the exception object is no
longer "CKCK: foo" but a TypeError.  :(
