Reduced testcase:

void abort(void);
struct S2495 {
    short int a;
    union{
        struct{
            _Bool d;
            int e:31;
        } c;
    } b;
};
struct S2495 x;
void foo(struct S2495 a) __attribute__((noinline));
void foo(struct S2495 a)
{
  if (a.a != x.a)
    abort();
  if (a.b.c.d != x.b.c.d)
    abort();
  if (a.b.c.e != x.b.c.e)
    abort();
}
int main()
{
  x.a = 30216;
  x.b.c.d = 1;
  x.b.c.e = 32766;
  foo(x);
  return 0;
