I can confirm gcc ICEs on this in 2.95.3, 3.0.4, 3.2.2, 3.2.3, 3.3.1 (20030707) and the mainline 
(20030724) so this is not a regression.

Dunno whether the code is valid or not.  C
language experts?

This is valid c as the initializer does not have to be a constant when it in a function.
Also this ICE on the C++ front-end too, so this is a middle-end problem, most likely 
related to bug 11852  (might even was fixed by it, I did not test GCC with the patch).  I will 
tentatively put the target as 3.3.2 and I will retest it when I bootstrap with updated sources 
with the patch already applied.

Guess what it is fixed by the same patch which fixed bug 11852  so commiting a testcase 
for this one.  Forgot to say this is fixed in 3.3.2 and 3.4.
