Visual D pipedmd error

[Random D user via Digitalmars-d-ide]

Hi,

for a while now I've been getting an error popup from Visual d 
when I build my project (and build succeeds). I've got no idea 
why or how it started (perhaps after some dmd update). Building 
works fine, but the error box is getting pretty annoying.
I'm running latest visual D in VS2013 community.

Anyways, here's the error:

core.exception.RangeError at pipedmd(286): Range violation
---------------

and no additional information... or debug logs.
