The DebugSuffix target on our Windows build seems to trigger a bug in the MSVC 2013 linker that causes explosive link times (on the order of three hours). It appears that this behavior is triggered by attempting to use the "/OPT:REF" and "/OPT:ICF" flags when building a debug target that is itself linking against other debug-targeted libraries. We do not encounter this on our release builds, or our debug target that does not reference debug support libraries. Our standard Debug build has these turned off “/OPT:NOREF, /OPT:NOICF”, which I think makes more sense for debug builds and should also be used on our "DebugSuffix" target.
