For the record,

Emacs 25.1 builds fine and runs fine under WSL providing you install all
the required packages.
I used :
 ../emacs/configure --with-jpeg --with-xpm --with-tiff --with-rsvg
--with-xml2 --with-gnutls --with-imagemagick --with-png=yes
and mobaxterm as an X server. Everything is ok. I could even load Spacemacs
with its about 100 packages.

Emacs master fails with the same configuration. It fails bootstrapping:

(gdb) run  --batch  --load loadup bootstrap
Starting program: /mnt/d/Source/emacs/build-emacs-ubuntu/src/temacs --batch
 --load loadup bootstrap
warning: Error disabling address space randomization: Succès

I must admit that I don't know how to read what gdb is reporting.
