8724,bad_alloc thrown in empty list copy constructor,gleonid@…,Ion Gaztañaga,"I am running RHEL 5.[[BR]]

Compiler - gcc 4.1.2[[BR]]

following code fragment compiled against boost 1.53.0 throws bad_alloc exception at run time.[[BR]]

Essentially I have an empty ::boost::container::list object allocated in shared memory (segment_manager from boost  interprocess).
attempt to copy such empty list causes bad_alloc exception

{{{
#include <boost/interprocess/allocators/allocator.hpp>
#include <boost/interprocess/managed_external_buffer.hpp>

namespace
{

typedef ::boost::interprocess::allocator<int, ::boost::interprocess::managed_external_buffer::segment_manager> int_allocator;
typedef ::boost::container::list<int, int_allocator> int_list;
char g_memory_buf[1024];

}

int main()
{
    ::boost::interprocess::managed_external_buffer segment(::boost::interprocess::create_only, g_memory_buf, sizeof(g_memory_buf));

    // 1. construct empty list
    int_list *l1 = segment.construct<int_list>(""1"")(int_allocator(segment.get_segment_manager()));

    // 2. use copy constructor
    segment.construct<int_list>(""2"")(*l1);

    return 0;
}
}}}

when same code is compiled against boost 1.51.0 - no exceptions.
I wonder if this behavioral change was intentional.
