Bug ID: 121851
Summary: ICE: in ocp_convert, at cp/cvt.cc:802
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: stevenxia990430 at gmail dot com
Target Milestone: ---
The following program successfully compiles on Clang but reports an internal
compiler error: in ocp_convert, at cp/cvt.cc:802. Failed on gcc-trunk.
To quickly reproduce: https://gcc.godbolt.org/z/EMnK3q8Ts
```
#include <exception>
#include <coroutine>
template<typename T>
struct Generator {
struct promise_type {
T current_value;
std::suspend_always yield_value(T value) {
current_value = value;
return {};
}
std::suspend_always initial_suspend() { return {}; }
std::suspend_always final_suspend() noexcept { return {}; }
Generator get_return_object() { return
Generator{std::coroutine_handle<promise_type>::from_promise(*this)}; }
void unhandled_exception() { std::terminate(); }
void return_void() {}
};
using handle_type = std::coroutine_handle<promise_type>;
handle_type coro;
Generator(handle_type h) : coro(h) {}
~Generator() { if (coro) coro.destroy(); }
};
Generator<int> const d(int n) {
int a = 0;
co_yield a;
}
int main() {
return 0;
}
```
