Actually  somebody has already described the problem on the mailing list and Paul Brook replied to that message. Hopefully you can find it in the archives.

Hi all.

I encountered the crash problem with windows build on Core-Duo host.
Qemu crashes in cpu_interrupt() called from host_alarm_handler() in vl.c
because CPUState *env = next_cpu is null.

I tried the patch to check env is not null in host_alarm_handler()
and now qemu does not crash.

       CPUState *env = next_cpu;
+       if(env) {
       /* stop the currently executing cpu because a timer occured */
       cpu_interrupt(env, CPU_INTERRUPT_EXIT);
#ifdef USE_KQEMU
       if (env->kqemu_enabled) {
           kqemu_cpu_interrupt(env);
       }
#endif
+       }
       event_pending = 1;
}

This is very temporary patch and I need to investigate
why next_cpu is null but sorry now I dont have enough time.

Thanks,
