irony process stopped

[xeechou]

Hi all, recently I tried to use emacs on windows at work for coding C++. My env is msys2 with mingw64. When I try to run emacs from msys2 shell with emacsclientw -na "" -c, I got the error msgs

irony-process stopped and

I/O task filter error: "spurious output", "Access is denied"

but I don't have the same problem if using emacs from runemacs.

But no matter whether I set w32-pipe-read-delay to 0 or not. I always got the warning anyway. Performance will be bad because a pipe delay is set for this platform.

Any help is really appreciate, thanks
