--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The reduced testcase contains:
```
  size_t tmp_len = ({
    size_t mod_multiply_len = ({
      sizeof(struct {        struct {        } temp_modulus;      });
    });
    sizeof(struct {
      struct {
        bigint_element_t element[(size)];
      } temp_exponent;
      uint8_t mod_multiply[mod_multiply_len];
    });
  });
  struct {
    uint8_t tmp[tmp_len];
  } __attribute__((packed)) * dynamic;
```
Which is the same VLA inside struct as what is in PR 112488 .
