Problem with boost::pool_alloc

        Hi!
 I  try  to  use  boost::pool_alloc  with  STLport-4.5-0119  snapshot.
STLPort  call  pool_alloc::allocate(const  size_type  n)  with  n = 0.
STLPort  naitive  allocator  returns in such case NULL, but pool_alloc
tries return memory.
Method simple_segregated_storage<SizeType>::try_malloc_n(
    void  *  & start, size_type n, const size_type partition_size) has
problem too if parameter n is 0. Problem is in while condition:
while (--n != 0)...

This simple program demonstrates a problem:

#include <boost/pool/poolfwd.hpp>
#include <boost/pool/pool_alloc.hpp>

typedef boost::pool_allocator<int> alloc_t;
int main(int argc, char* argv[])
{
        alloc_t alloc;
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        alloc.allocate(0);
        return 0;
}

How can I solve this problem?
Thanks
