Thanks, Robert, that worked. I'll summarize the case here in case anyone
encounters similar problem.
We needed to read binary archives created on a different platform.
Changing the code to use portable_binary_archive was not an option - the
data was already written to disk. The problem turned out to be in string
serialization code, which depended on the size of std::size_t type.
Therefore, replacing the std::size_t with unsigned int in these two
files allowed us to read the archive on 64 bit platform.
The sizes of different types on our platforms were as follows :
type vc8 vc8-x64
------ ------ -------
void* 4 8
size_t 4 8
int 4 4
