Does the native app use JIT and have no problems with Windows DEP? Does PHP need some Cygwin specific patches to re-mmap JIT code as rx, or Cygwin patches so Windows sees mmap rx regions as executable code, or otherwise "blesses" JIT code so it is not crashed by DEP? There should at least be some way to indicate there is a DEP issue rather than just crashing with a segv! -- Take care.
