The problematic symbol is CryptoPP::IteratedHashBase<unsigned long, CryptoPP::HashTransformation>::~IteratedHashBase() which is defined virtual in the header file. Moving the definition to .cpp file could workaround the issue. Looks like IR linking tripped on multiple definitions of virtual method definitions or dtor is special in this case. Investigating.
