[Qemu-devel] Fiber switching and stack protection

[Pavel Dovgaluk]

Hello.

 

Recently I tried to build qemu-1.0 with MinGW and start it with qcow file created with previous version of qemu.

But after starting guest Windows loading process qemu had closed because of an exception.

 

I figured out that this exception is “stack smashing” and it happened in qemu_coroutine_switch of coroutine-win32.c file.

But when I remove -fstack-protector-all option from makefile nothing changes – an exception occurs again.

 

Does anyone have an idea about such behavior?
