Confirmed, here is the reduced testcase:
int bad[100];

int level;
int count;

static inline int g(int *idx)
{
    int m;
    int i;

    do {
	m=0;
	i=*idx;
	switch(i) {
	    case 0:
		i++;
		m=1;
		break;
	}
	*idx=i;
    } while(m<0);
    return m;
}

int f()
{
    int i;

    i=0;
    for(;;) {
	int m;
	m=g(&i);
	if(m==0) break;
	if(level==0 && bad[m])
	    continue;
	count++;
      }
    return 0;
}
