LNK4255 warning - should I be concerned?

[DanielG via Digitalmars-d-learn]

"warning LNK4255: library contain multiple objects of the same 
name; linking object as if no debug info"

Is there some way to get more detail about this warning? Might 
help to know which objects ...

My program is working fine now, but is this going to cause 
problems later on? Like when I want to debug?
