--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed. reduced valid testcase:
```
struct a {
  __attribute__((no_sanitize("")))
  int f(int) [[pre:true]];
};
int a::f(int) {}
```

Looks like there is a missing check for cxx_contract_attribute_p in the loo=
p.


has_active_contract_condition either should use cxx_contract_attribute_p  or
more likely just use CONTRACT_CHAIN .=
