Those are normal and can be ignored.

Those I saw just recently and I don't have a good idea why they show up. The 
function in question (LaGenMatDouble::operator=) exists and its 
implementation exists as well. If you use the dependency walker 
(depends.exe), you will find this symbol in the lapackpp32.dll as well. On 
Linux there is no such problem, so unfortunately I don't know how to fix this 
at this point in time.
