          Issue ID: 15187
           Summary: dispose for allocators is broken
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: major
          Priority: P1
         Component: phobos
          Assignee: nobody at puremagic.com
          Reporter: ilyayaroshenko at gmail.com

Current code:
================
void dispose(A, T)(auto ref A alloc, T* p)
{
    static if (hasElaborateDestructor!T)
    {
        destroy(*p);
    }
    alloc.deallocate(p[0 .. T.sizeof]);
}

Should be:
================
void dispose(A, T)(auto ref A alloc, T* p)
{
    static if (hasElaborateDestructor!T)
    {
        destroy(*p);
    }
    alloc.deallocate((cast(void*)p)[0 .. T.sizeof]);
}
