And here is a semi reduced/self-contained source which I came up after debuggin this a
little bit:
struct cset_converter { int func; int cd; };
void abort(void); int puts(const char*);
int f(int i){return i;}
void g(void){puts("hi");}
struct conversion
{
int pair;
int func;
int fake_cd;
};
static const struct conversion conversion_tab[] = {
{ 2, 2, 2 },
{ 3, 3, 3 }
};
static struct cset_converter
init_iconv_desc (int i)
{
struct cset_converter ret;
unsigned i1;
char *pair;
if (!i)
{
ret.func = 0;
ret.cd = 0;
return ret;
}
pair = __builtin_alloca(i*3);
for (i1 = 0; i1 < (sizeof (conversion_tab) / sizeof ((conversion_tab)[0])); i1++)
if (i == conversion_tab[i1].pair)
{
ret.func = conversion_tab[i1].func;
ret.cd = conversion_tab[i1].fake_cd;
return ret;
}
ret.func = 2;
ret.cd = f(i);
if (ret.cd == 4)
{
g();
ret.func = 4;
}
return ret;
}
struct f
{
struct cset_converter a;
struct cset_converter b;
};
void ff(struct f *a)
{
a->a = init_iconv_desc(0);
a->b = init_iconv_desc(1);
}
int main(void)
{
struct f a;
ff (&a);
if (a.a.func!=0 || a.a.cd !=0)
abort();
if (a.b.func!=2 || a.b.cd !=1)
abort();
return 0;
}
