Following code (f()) if compiled with -fno-exceptions should
produce only one initialization boolean for all local
static variables, not one per variable. This is since
they always initialized together provided there are no exceptions.
If exceptions are allowed then it should be driven by
the flag in constructors saying if they allow exceptions or not.

struct C {
C();
int get();
};
int f() {
static C i;
static C j;
return (i.get() + j.get());
}
