--- Comment #2 from Nathan Sidwell <nathan at gcc dot gnu.org> ---
Thanks for checking this didn't seem a duplicate!
Reduced tescase:
// 99170_a.H
namespace STD {
class string {
public:
template <typename T>
string (const T *);
};
}
// 99170_b.C
export module test;
import "99170_a.H";
export class A {
STD::string str{"ayyy"};
};
./cc1plus -fmodule-header -quiet -std=c++17 99170_a.H && ./cc1plus -fmodules-ts
-quiet -std=c++17 99170_b.C
