Actually there is a call clobbering issue here or something like that because I
see now where the address of multilib_exclusions_raw escaping (I have to look
where we mark the variable as call clobbering).

With Paolo's testcase we get the following tree dump in .ch (after copy loop
header):
g (o)
{
static const char * const multilib_exclusions_raw[1] = {0B};
const char * const * q;
static const char * c

Reduced testcase:
static const char *const multilib_exclusions_raw[] = {0};
struct obstack {
char *next_free;
};
static struct obstack multilib_obstack;
int main (int argc, const char **argv)
{
const cha

Even more reduced:
extern void f(char *const *);
void g (char **o)
{
static const char *const multilib_exclusions_raw[] = { 0 };
const char *const *q = multilib_exclusions_raw;
f (o);
while (*q++)
