Hi
I wanted to check some new stuff from C++20 so I've compiled GCC 11 form git
and wrote some test app. GCC version:

gcc version 11.0.1 20210407 (experimental) (GCC) 

This is the main.cpp file that I've created:

#include 
#include 

import test;

int main()
{
std::string str = "Hello";

std::cout << str << std::endl;
return 0;
}

And this is the test.cpp:

module;

#include 
#include 

export module test;

template 
concept IsStdString = std::is_same_v;

Command line:
c++ -std=c++20 -fmodules-ts test.cpp main.cpp

Compiler doesn't throw any error but when I'm trying to exec app it gives me an
error:

[1]71397 segmentation fault (core dumped)  ./a.out

If I remove concept part from test.cpp or move it into main.cpp app is working
fine.
I think it's a bug but it's new stuff in language so maybe I don't understand
something

Best regards
