This one is really weird.  It turns out that the value must be used in a
unittest, etc, as per the test case, and the error actually goes away if I
change the module name to be larger than 4 characters.  This is a new bug, as
the test this is derived from used to pass without error:

C:\code\src\d\bugs>type 161x.d
template testStoreIf( T )
{
    void testStoreIf( T val = T.init + 1 )
    {
        T base;
        assert( atomicValueIsProperlyAligned!(T)( cast(size_t) &base ) );
    }
}
import std.c.stdio;

template atomicValueIsProperlyAligned( T )
{
    bool atomicValueIsProperlyAligned( size_t addr )
    {
        printf( "%p %% %u = %u\n", addr, T.sizeof, addr % T.sizeof );
        return addr % T.sizeof == 0;
    }
}


unittest
{
    testStoreIf!(long)();
}


void main()
{

}
