[Qemu-devel] [Bug 916720] Re: select fails on windows because a non-socket fd is in the rfds set |

I am still seeing the symptoms that Arie pointed out:
Remote debugging using :1234
Ignoring packet error, continuing...
warning: unrecognized item "timeout" in "qSupported" response
Ignoring packet error, continuing...

Malformed response to offset query, timeout
I started QEMU like:
arm-none-eabi-qemu-system.exe -gdb
tcp:127.0.0.1:1234,nowait,nodelay,server,ipv4 -S -semihosting -kernel
hello.out
This was with an ARM EABI system emulator that I built from today's
mainline. From a brief look it seems like QEMU is going into 'g_poll'
and never coming out.

Title:
select fails on windows because a non-socket fd is in the rfds set
Status in QEMU:
Fix Committed
Bug description:
The select call in file main_loop.c at line 460 fails on windows
because a non-socket fd is in the rfds set. As a result, gdb remote
connections will never be accepted by qemu. The select function
returns with -1. WSAGetLastError returns code 10038 (WSAENOTSOCK).
I start qemu as follows:
qemu-system-arm -cpu cortex-m3 -M lm3s6965evb -nographic -monitor null
-serial null -semihosting -kernel test1.elf -S -gdb tcp:127.0.0.1:2200
qemu is configure with:
CFLAGS="-O4 -march=i686"
configure --target-list="i386-softmmu arm-softmmu sparc-softmmu ppc-softmmu"
--prefix=/home/qemu/install --cc=mingw32-gcc --host-cc=mingw32-gcc
--audio-drv-list="dsound sdl" --audio-card-list="ac97 es1370 sb16 cs4231a adlib
