3934,serialization assertion failure on windows using DLLs,cris@…,Robert Ramey,"On Windows I get an assertion failure in void_cast.cpp line 225 with the following scenario:

DLL 1 has concrete class C which inherits from virtual B, which inherits from virtual A. BOOST_CLASS_EXPORT(C) is used.

a static C exists.

DLL 2 has concrete class D which inherits from virtual B.  BOOST_CLASS_EXPORT(D) is used.

a static D exists and will be instantiated when the library is loaded.

main.cpp - contains an instantiation of D to make main.exe depend on both DLL 1 and DLL 2.
