I don't have any particular insights to add other than to say 
that we have had similar problems with Windows and recent DMD 
releases. It's very hard to reduce. We had no problems with dmd 
2.087.1, but when we were trying to update to any compiler after 
that we had to switch one build to use ldc instead to avoid this 
problem. Pegged was not involved in this build.
