 Hi,

 We believe that there is a memory leak in
 boost::interprocess::winapi::c_heap_deleter::realloc_mem

 boost/interprocess/detail/win32_api.hpp:1790-1797
 {{{
 void realloc_mem(std::size_t num_bytes)
    {
       void *buf = ::realloc(m_buf, num_bytes);
       if(!buf){
          free(m_buf);
          m_buf = 0;
       }
    }
 }}}

 should probably be

 {{{
 void realloc_mem(std::size_t num_bytes)
    {
       void *buf = ::realloc(m_buf, num_bytes);
       if(!buf){
          free(m_buf);
          m_buf = 0;
       }
       else {
          m_buf = buf;
       }
    }
 }}}
