[Qemu-devel] stack smash while using SDL 1.2.5 with QEMU 2.9

[Taimoor Mirza]

Hi Guys,

I have been using QEMU 1.5 earlier with SDL version 1.2.5. Now we have
decided to move to new version of QEMU. I have built QEMU binaries with SDL
support using SDL 1.2.5 that we were using earlier. Windows binaries work
fine but I get stack smash in sdl.c on Linux. Below are stack traces that I
have got from GDB:

Program received signal SIGABRT, Aborted.

I want to know whether it is a known issue and Is QEMU 2.9 compatible with
SDL 1.2.5?

Thanks,
