I'm not aware of any reason that increasing the stack size should make things 
worse.  But I don't understand these crashes anyway, so who knows?  If you want 
to experiment, you can restore the previous stack size with the command

  peflags -x0x400000 /usr/bin/emacs-X11.exe

(My builds for the x86_64 Cygwin distribution have been using a 4MB stack size 
for over a year.)
