The problem can be reduced to the following testacse:
==================================
int Sum(int);
template<int> struct A
{
int X[Sum(2)];
void foo() { sizeof(X); }
};
void bar()
{
A<0> a;
a.foo();
}
==================================
The code is invalid, since the array size "Sum(2)" is not a constant.
Even the definition
inline int Sum(unsigned int n) { return n*(n+1)/2; }
from the original test case doesn't change this.
The ICE was fixed by Mark's patch for PR 18429
http://gcc.gnu.org/ml/gcc-cvs/2004-11/msg00582.html
We now (i.e. in gcc 4.0.0) emit a proper error message.
Closing, since this is not a regression.
