Bug ID: 104020
Summary: [coroutines] ICE in co_await function call with
initializer_list arguments
Product: gcc
Version: 11.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: me at xecycle dot info
Target Milestone: ---
Running example at https://godbolt.org/z/cEjTWPvYf, code with clang part
removed is:
#include <coroutine>
using std::coroutine_handle;
using std::suspend_always;
using std::suspend_never;
#include <initializer_list>
#include <string_view>
struct promise_t;
struct ret_t {
using promise_type = promise_t;
};
struct promise_t {
ret_t get_return_object() { return {}; }
constexpr auto initial_suspend() noexcept { return suspend_never(); }
void return_void() {}
auto final_suspend() noexcept { return suspend_never(); }
void unhandled_exception()
{
__builtin_trap();
}
};
auto operator co_await(ret_t)
{
struct W {
auto await_ready() { return std::true_type(); }
void await_suspend(coroutine_handle<>) {}
void await_resume() {}
};
return W();
}
ret_t f1(std::initializer_list<std::string_view>)
{
co_return;
}
ret_t f2()
{
co_await f1({"abc", "def"});
}
ICE in 11.2, "array used as initializer" in trunk.
Can compile if either:
- the argument is std::initializer_list<int>, or
- use a separate variable, like
std::initializer_list<std::string_view> args {"abc", "def"};
co_await f1(args);

As Avi says, this is a dup of 98056.
