Which version of XL C++ is that? 9.0? What is the value of __IBMCPP__?

[Peter Dimov]

Actually 12.1 would be a better guess, I think. :-)

Hubert Tong from IBM Canada reports that:

Using the following test case as a reference:

template< class T > struct sp_dereference;
template< class T > struct sp_dereference< T[] > { typedef void type; };
template< class T, unsigned long N > struct sp_dereference< T[N] > { typedef void type; };

int main() {
   (sp_dereference<int []>::type)0;
   (sp_dereference<int [42]>::type)0;
}

The issue described cannot be reproduced with the following versions of XL C/C++ for AIX:

9.0.0.8
10.1.0.2
11.1.0.0
12.1.0.0

Note that for v9.0 and v10.1, the issue is reproducible on older levels of the release.

Seems that we don't need to do anything for this ticket.
