Bug ID: 105446
Summary: [modules] Partitions: Segfault
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: deco33000 at yandex dot com
Target Milestone: ---
Hi,
I have a segfault at runtime with no compilation issue, even without calling
the function in the partition:
-----------
mod.cxx:
module;
#include <iostream>
#include <string_view>
#include <string>
export module hello;
export import :sub_mod;
namespace X {
inline unsigned gv = 52;
void greeter2 ( std::string_view const &name ){
std::string h = "non exported greeter";
std::cout << "Bye" << name << "!" << h << "\n";
// Y::g();
}
}
export {
namespace X {
void greeter ( std::string_view const &name ){
std::string h = "exported greeter";
std::cout << "Hello " << name << "!" << h << "\n";
greeter2("greet2");
}
}
}
-----------
mod_sub.cxx:
module;
#include <iostream>
export module hello:sub_mod;
namespace Y {
auto g (){
std::cout << "in out" << std::endl;
}
}
-----------
main.cpp
import hello;
int main ( void ){
X::greeter( "world" );
return 0;
}
-----------
compilation:
/path/custom/g++ g++ -std=gnu++20 -fmodules-ts mod_sub.cxx mod.cxx main.cpp
Result: Segfault at runtime.
Thanks,
