            Bug ID: 103256
           Summary: Internal compiler error after using iostream and
                    filesystem as modules
           Product: gcc
           Version: 11.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hrominium at gmail dot com
  Target Milestone: ---

The compiler crashes with "inernal compiler error" while compiling the
following program:

```
import <iostream>;
import <filesystem>;

namespace fs =3D std::filesystem;


int main(int argc, char* argv[]){
    fs::path input =3D "./";
    std::cout << input;
    return 0;
}
```

Compiled with:
g++ -c -std=3Dc++20 -fmodules-ts -x c++-system-header filesystem iostream
g++ -std=3Dc++20 -fmodules-ts -o test test.cpp


GCC versions:
11.1 (archlinux)
11.2 (selfcompiled from gcc's git repo)=
