Bug ID: 94752
Summary: [coroutines] compiler ICE with coroutine with unnamed
parameter
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: lewissbaker.opensource at gmail dot com
Target Milestone: ---
See https://godbolt.org/z/QCXqeo
Compile the following source code with GCC trunk.
Flags: -std=c++20 -fcoroutines
-----
#include <coroutine>
using namespace std;
struct task {
struct promise_type {
promise_type() {}
task get_return_object() { return {}; }
suspend_never initial_suspend() { return {}; }
suspend_never final_suspend() { return {}; }
void return_void() {}
void unhandled_exception() {}
};
};
task foo(int) {
co_return;
}
-----
Results in an internal-compile-error - segmentation-fault.
Pointing at closing curly-brace of 'foo()'.
Seems to be related to the parameter being unnamed as naming
the parameter results in this code compiling successfully.

The master branch has been updated by Iain D Sandoe <iains@gcc.gnu.org>:
https://gcc.gnu.org/g:29f55115583a0dab6cbac749c4f0804fd88e9536
commit r10-7973-g29f55115583a0dab6cbac749c4f0804fd88e9536
Author: Iain Sandoe <iain@sandoe.co.uk>

coroutines: Do not assume parms are named [PR94752].
Parameters to user-defined coroutines might be unnamed.
In that case, we must synthesize a name for the coroutine
frame copy.

* coroutines.cc (morph_fn_to_coro): Ensure that
unnamed function params have a usable and distinct
frame field name.
