   Thanks for the report! This is currently the right place to get in touch right now since I haven't setup a separate repo for issues tracking yet.

   In my case it is a member variable of the base class, not sure if that is relevant.

   This sounds like a good first suspect indeed.

   Could you please share a minimal reproduction sample?

   I tried to extract the situation from my program and it also happens with this small example:

   #include <Eigen/Core>
   
   struct Base {
   	Eigen::Vector3d baseMember;
   };
   
   struct Test : public Base {
   	void f() {
   		Eigen::Vector3d local;
   		// Break here.
   	}
   
   	Eigen::Vector3d member;
   };
   
   int main()
   {
   	Test().f();
   }

   When breaking in f, I can plot local and member, but baseMember gives

   OID: could not plot 'Base.baseMember': no inspector matched 'Base.baseMember'
