Andreas, will an attribute((destructor)) work ? Cos if it does you can put your printf pretty much anwhere rather than vl.c

 I am afraid first_cpu (CPUArchState) is got poisoned, too. :/
Even I comment out CPUArchState from poison.h,

--- vl.c
extern CPUArchState *first_cpu;

static void main_loop(void)
   ... snip ...

   printf("%d", first_cpu->created);

I still get compilation error below,

/tmp/chenwj/qemu/vl.c:1548:20: error: expected '=', ',', ';', 'asm' or '__attribute__' before '*' token
/tmp/chenwj/qemu/vl.c: In function 'main_loop':
/tmp/chenwj/qemu/vl.c:1568:18: error: 'first_cpu' undeclared (first use in this function)

 Any thought on what I am missing? Thanks.
