------------------------------------------------------+---------------------
 I have a 32 bit build (Linux) of my application that uses a
 managed_shared_memory.  I follow very closely to the examples on the
 "Quick Guide for the Impatient" page.  However, when I run the binary on
 some 64 bit machines (Linux), it intermittently fails to open a previously
 existing shared memory object, throwing an exception that claims "Value
 too large for specified format."  I debugged it in gdb, and found that the
 ::fstat command in function get_file_size in
 boost/interpocess/detail/os_file_functions.hpp was getting an error, with
 the specified error string.  I have the strong suspicion that it is a
 matter of a 64 bit machine misinterpreting the input parameter from a 32
 bit call.  I am running on a SUSE 9 based Linux distribution in x86_64
 mode in a 2.6.X kernel.
