This sounds like a C++ version of the Java issue fixed with r189<http://code.google.com/p/protobuf/source/detail?r=189>: the encoded descriptor data in the generated file exceeded the Java string literal limit. This large descriptor was previously built in C++ but was removed from the test suite in a later revision. Kenton, do you recall if you ever ran the test with VC++2005? Just wondering if it only shows up in certain environments/settings.
