Admittedly I am alternating between building debug and unittest 
builds, but I'm only using dub, no separate compilation. I have 
limited control of the version specifiers other than through the 
build configurations, so there's not a whole lot to mix.

     $ dub clean
     Cleaning package at C:\cygwin\home\zorael\src\kameloso...

     $ dub build -c cygwin -a x86_64
     Performing "debug" build using dmd for x86_64.
     kameloso 1.0.0-beta.2+commit.57.g90fdd1d: building 
configuration "cygwin"...
     Linking...
     kameloso.obj : fatal error LNK1179: invalid or corrupt file: 
duplicate COMDAT

     Error: linker exited with status 1179
     dmd failed with exit code 1179.

None of the (version specifiers in the) build configurations I 
have touch upon the part of the fairly innocent code mentioned in 
the error message, if I'm reading it right.
