Summary: coroutine ts crash
Product: kdevelop
Version: git master
Platform: Gentoo Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Language Support: CPP (Clang-based)
Assignee: kdevelop-bugs-n...@kde.org

Target Milestone: ---
example from https://isocpp.org/files/papers/N4663.pdf
#include <experimental/coroutine>
#include <iostream>
struct generator {
struct promise_type;
using handle = std::experimental::coroutine_handle<promise_type>;
struct promise_type {
int current_value;
static auto get_return_object_on_allocation_failure() {
return generator{nullptr};
}
auto get_return_object() {
return generator{handle::from_promise(*this)};
}
auto initial_suspend() {
return std::experimental::suspend_always{};
}
auto final_suspend() {
return std::experimental::suspend_always{};
}
auto yield_value(int value) {
current_value = value;
return std::experimental::suspend_always{};
}
void unhandled_exception() { std::terminate(); }
// void return_void() {}// uncomment -> crash
};
bool move_next() {
return coro ? (coro.resume(), !coro.done()) : false;
}
int current_value() {
return coro.promise().current_value;
}
~generator() {
if(coro) coro.destroy();
}
private:
generator(handle h) : coro(h) {}
handle coro;
};
generator f() {
co_yield 1;
co_yield 2;
}
int main() {
auto g = f();
while(g.move_next()) std::cout << g.current_value() << std::endl;
}
Also, crash on all other examples. The compilation passes normally.
