--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I suspect the issue is for LTO we don't stream out the ignore part .

Anyways confirmed, you can reproduce it with the following single file
testcase:
```
typedef struct st_mysql_bind
{
  int t;
  int t1;
  int t2;
  int t3;
} bb;

[[gnu::noipa]]
void *f(unsigned long paramCount)
{
    if (paramCount =3D=3D 0)
      return nullptr;
    return new bb[paramCount]();
}

int main(void)
{
  f(100);
}
```
Compile it with `-flto -W -Wall -O2` and see the warning.=
