Use this reduced testcase, but please verify this in your end again.
For the code change part, I would like to let other to review :P
struct a {
int b;
int c : 1;
int : 1;
} d();
typedef struct
{
int e;
struct {
int f;
};
} g;
int i;
char k, l, n;
void *m;
char *o;
void h();
char *j();
void p(int buf, __builtin_va_list ab, int q) {
do {
void *r[] = {&&s, &&t, &&u, &&v, &&w};
int c;
goto *m;
s:
c = 1;
while (1) {
t:
u:
ae:
void *af = __builtin_va_arg(ab, void *);
h(p);
o = j(i);
if (o == 0)
goto ae;
l = 'S';
break;
v:
g ah;
__builtin_memset(&ah, '\0', sizeof(g));
h(n, __builtin_va_arg(ab, int), &ah);
break;
w:
if (__builtin_expect(q, 0))
c = 0;
struct a ai = {'S', c};
d(buf, ai, af);
}
} while (k);
}
