Re: [Qemu-devel] [Bug 1182490] [NEW] [qemu-1.5] coroutine-win32.c broken on NULL pointer

[Dongsheng Song]

When I use qemu 1.4, it running smoothly:

SET PATH=E:\opt\qemu-1.4.1-win64
SET QEMU_LD_PREFIX=E:\opt\qemu-1.4.1-win64

E:\var\tmp\armhf_wheezy_qemu>qemu-system-arm -M vexpress-a9 -cpu
cortex-a9 -m 512 -uuid e04ec652-8bed-11e2-86b9-000c290c10de -drive
file=armhf_wheezy.img,if=sd,cache=writeback -kernel
vmlinuz-3.2.0-4-vexpress -initrd initrd.img-3.2.0-4-vexpress -append
"root=/dev/mmcblk0 rw init=/sbin/init"
