C++: namespace ep { struct Instance {}; Instance *s_pInstance = nullptr; } D: extern (C++, ep) { struct Instance {} extern __gshared Instance* s_pInstance; } C++ mangles: ?s_pInstance@ep@@3PEAUInstance@1@EA D mangles: ?s_pInstance@ep@@2PEAUInstance@1@EA Notice there is a '2' where a '3' should be.

I ran into the same problem. Simpler reproducer: D: extern (C++, ep) extern __gshared int variable; C++: namespace ep { int variable; }

Bootcamp hint: start looking at `mangleVariable` in `VisualCPPMangler` in cppmangle.d.
