Comment (by Joao Geada <joao@…>):

 I'm stunned incredulous by the attitude displayed here Markus.

 I've contributed a testcase that shows that there is still a problem with
 the current version of boost serializer to read binary archives produced
 by an older version. This testcase was requested by Ramey, which I've
 spent time minimizing and clearing with my company to be allowed to share
 it with this team. In virtually every other open source project I'd be
 thanked for this and other people more expert with the code would dive in
 and diagnose what the real problem is etc etc.

 Instead here you '''complain''' for my having provided you a testcase???

 And once again, let me be clear as to what exactly this testcase shows:

 1) binary serialization written by 1.34.1 cannot be read by 1.53

 2) binary serialization written by 1.34.1 can be read by 1.34.1; likewise
 binary written by 1.53 can be read back by 1.53. I'd have thought it
 obvious that this should work, but as you'll see later, such an assumption
 is not legitimate in all cases.

 3) text serialization written by 1.34.1 can be read by 1.34.1 and 1.53.
 Text archive written by 1.53 can also be read back by 1.53.

 4) xml serialization written by 1.34.1 cannot be read by 1.53, but can be
 read back by 1.34.1.

 5) xml serialization written 1.53 cannot be read back by 1.53!!! There
 goes that assumption that read/write within the same version and same
 backend format works.

 6) the serialization code all lives in a single piece of code, runs in
 Linux 64bit; the problem here does not appear in any way related to bug
 5579. But I'm not deeply familiar with the boost serializer code so I
 could be wrong about that.

 Note that I work for a closed source company and cannot under any
 circumstances reveal any of the our code.

 Echoing similar sentiments elsewhere, I'm seriously starting to wonder if
 my team has made a major mistake in using and relying on this component.
