This should be ice-on-invalid-code.  The code:

    bar<evil>()();

must be replaced with:

    bar<&Dummy::evil>()();

because 'evil' alone is not a valid pointer-to-member function.
GCC compiles file with the corrected code.

Well, it's not really a regression, since GCC accepted the code before 3.4.0.

> Well, it's not really a regression, since GCC accepted the code before 3.4.0.

Even though we acceted it before 3.4.0, this is a regression in that we should not change anything to an 
ICE.
