The following valid code snippet is rejected by mainline:
====================================
template<typename T> struct A
{
static const T i = 1;
char a[int(i)];
};
====================================
The error message is:
bug1.cc:4: error: array bound is not an integer constant
Mark, this is similar to PR19826 which you already fixed, but with an
additional cast.
For the same reason the following testcase fails, too:
==================================
template<int> struct A {};
template<typename T> struct B
{
static const T i = 2;
A<int(i)> a;
};
==================================
bug2.cc:6: error: template argument 1 is invalid
Due to this problem the testcase in PR19297 still fails on mainline.

Note that this bug breaks BOOST.
Here is a reduced testcase, which comes from boost/mpl/aux_/integral_wrapper.hpp:
------------------ begin testcase
template< typename T, T N >
struct integral_c
{
static const T value = N;
typedef integral_c< T, static_cast<T>((value + 1)) > next;
// typedef integral_c< T, static_cast<T>((value - 1)) > prior;
// operator T() const { return static_cast<T>(this->value); }
};
------------------- end testcase
% g++-cvs testcase.C
c.C:6: error: template argument 2 is invalid
The original error was obtained by including <boost/numeric/ublas/matrix.hpp>
The following error was recieved:
In file included from /usr/include/boost/config.hpp:35,
from /usr/include/boost/numeric/ublas/config.hpp:24,
