Yes, I do:

My suspicion is that the added compiler and linker flags taint the .obj files in some way that subsequently breaks the compilation.  It may be down to a conflict between the new security flags and link time code generation (so the .obj files are in some "intermediate form").  I didn't try making another code modification and rebuilding after I had gotten my build with /t:Rebuild to work, so I've kicked off one now (unfortunately the update to master has pulled in some CMake changes as well so the regeneration is running which might invalidate my attempt to replicate.

Failed in the same way.  Might have to try to make a minimal repo and report to MS.
