Visual D optilink issue

[Illuminati via Digitalmars-d-ide]

I have been getting this issue quite often lately. It just 
started happening for for some reason. It happens about every 5 
builds:

OPTLINK : Error 3: Cannot Create File Win32\Debug DMD\test.map

If I immediately build afterwards, it works. I have added `.map` 
to the clean files option.

I have tried with the VS debugger and mago. I thought it 
initially started when I switched to the VS debugger so I 
switched back to mago but it continued.

I also might have changed some settings somewhere such as 
creating a "full" map file. Not quite sure what started it all. 
Seems like a bug regardless since it rebuilds fine most of the 
time(with no source changes).

Any ideas?
