Comment (by Chris Rusby <chris.rusby@…>):

 Based on the above, I am of the opinion that I (the user) need to tell the
 boost serialization libraries whether to export the implementation of the
 instantiated template from the DLL. I envisage adding a new macro that I'd
 use something like this:

 BOOST_CLASS_EXPORT_KEY3(TestObject, "TestObject", CRASHTESTDLL_EXPORTS)

 This would __declspec(dllexport) the instantiated TestObject serialization
 templates from the DLL (because CRASHTESTDLL_EXPORTS would be defined),
 and from the main program would __declspec(dllimport) the serialization
 templates and hence import from the DLL.  Hence there would be one and
 only one implementation of iserializer<Archive,TestObject?> (which seems
 to be the root cause of my problem).

 I've not verified that this works, I'm afraid, but I hope to soon.  If it
 does work, though, the advantage is that it's not going to modify existing
 code so is much lower risk.

 Thanks,

 Chris

 PS In answer to your (Robert) original question, when I understand it
 fully i.e. when this is fixed and I understand why/how it's fixed, I'd be
 more than happy to do some documentation for you.
