It has never been legal.  Yes, legacy codes abuse the dummy argument 
syntax of X(1) to mean X(*), but it has never been legal to access
X(2) if you declared the dummy argument as X(1).

> Like Dominique in Comment #6, I'd urge you to fix this.

If you re-read my original comment, you'll note that I stated that
gcc should never ICE.  This would imply that, yes, gcc should be 
fixed.
