ICE on invalid with procedure interface

[Janus Weil]

Hi Andrew,

I can confirm this ICE with 4.5, 4.6 and trunk. Could you please open
a PR in bugzilla?

Do you have any compiler which manages to detect this?

Spontaneously, I would tend to agree with you. So this may be yet
another bug. Once the ICE is fixed, we should check if this also
happens with more recent gfortran versions.

What I find even more puzzling is that your program is even accepted
by gfortran 4.3 (which IIRC does not support procedure pointers yet)
...

Cheers,
