Yes, I was using the emacs-26 branch too. However, I'm not using 
-DGC_MCHECK as it does not work at all on Fedora; I don't know why and I 
have no plans to look into it as GC_MCHECK is an obsolete hack (people 
should be using gcc -fsanitize=address in the master branch). So, I 
suggest that you stop using -DGC_MCHECK on MS-Windows and see whether 
that fixes your problem.
