c++ - Bug: mistakes compile-time multiplication in template param list for VLA

Compiling STLSoft's static_array classes gives

    H:\STLSoft\Identities\STLSoft\stlsoft\stlsoft_static_array.h(730) 
: Error: variable length arrays are only for function prototypes and 
autos

Essentially, the class template is declared like this

template<   typename T
        ,   size_t N0
        ,   size_t N1
        ,   size_t N2
        ,   size_t N3
        ,   typename P   =   do_construction<T>
        ,   typename M   =   T[N0 * N1 * N2 * N3]
        >
class static_array_4d
{

    . . .

    M   m_data;    // <= This is the line (730) that causes the 
problem
};


I've tried boiling it down, but it eludes me. I've included a test 
file incorporates the same structure, but fails to elicit the error

It'd be great if this can be found and fixed for 8.44, as I suspect 
STLSoft 1.8.4 will be releasable at the same time.

Cheers

I'm afraid that a test case that doesn't produce the error is not terribly useful.
