I fixed it using the union trick.

But I think there might be another solution. The standard states in  
5.3.4.10 that arrays of char's allocated with new expression are always  
properly aligned for types whose size is no greater than the size of the  
array. Does allocator<char>::allocate() have the same requirement? I could  
not find it in my copy of the standard.
