Comment(by Doug Wallas):

 The problem seems to be on the >> operator.
 The library do read from the stream, but does not check after reading that
 the stream had not encoutered an error while reading. The >> operator then
 starts creating a new object from what he just read and sigfaults :(

 I may be wrong, but i think the fail() is updated after a read, so the
 check on _stream->fail() would be ok (the library already does one in
 internal) and the crash would still occur.
