Bug ID: 121179
Summary: When importing std, chrono calculation will cause a
compilation error
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: printfne at gmail dot com
Target Milestone: ---
// when there are no errors
// time.cppm
module;
#include <algorithm>
#include <chrono>
#include <functional>
#include <mutex>
#include <chrono>
export module time;
export class Time {

public:

// ... operate 'ymd' and 'hms'
time_ = typename

+ hms.to_duration());
}
};
// command when there are no errors
g++-latest -std=gnu++26 -c -fmodules time.cppm
// using import std will result in a compilation error
// time.cppm (just modify include to import std)
