static declaration not working in macro

Hi! I try to use a static int to count the number of times a function is called. The example is below:

void ex ()
{

Int_t result = -1;
result = blah();

cout << result << endl;
cout << count << endl;
}

Int_t blah ()
{

static Int_t count = 0;
count++;
return count;
}

root [0]
Processing ex.C...
1
Error: Symbol count is not defined in current scope ex.C:7: (class G__CINT_ENDL)34877216
*** Interpreter error recovered ***

AFAIK count should have been known and printed .. is it something that i am missing? (v5-28-00d)
Thanks,
Adrian
