Yes, all succeeded except the forktest, which I guess doesn't work on Windows
anyway.  I've tried it with both mingw64-i686, mingw64-x86_64 msvcrt and ucrt
version, the 32bit Emacs build doesn't crash.

Both 8 and 16 passed the mps's test suite and both crash Emacs at
temacs bootstrap
in my case.  I'm using this to run the test suite btw
    ../tool/testrun.sh -s testrun w3i6gc/cool

It would be great, I'm using the tip of scratch/igc branch merge with
master.  The
tree is here https://github.com/kiennq/emacs/tree/scratch/igc
