Bug ID: 107955
Summary: ICE: trying to capture ‘ARGS#0’ in instantiation of
generic lambda
Product: gcc
Version: 12.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: onebit74 at gmail dot com
Target Milestone: ---
The code is valid
If you comment out the if, it compiles.
If you comment out the branches in the if, it compiles as well.
But somehow putting them together gives ICE.
#include <functional>
template<typename F>
struct agg_p {
F f;
void _parse(auto...ARGS){
[&](auto...P_ARGS){
using result =
std::invoke_result_t<F,decltype(ARGS)...,decltype(P_ARGS)...>;
if constexpr(!std::same_as<result, void>){
f(ARGS...,P_ARGS...);
}else{
f(ARGS...,P_ARGS...);
}
}(1);
}
};
int main(){
auto add = [](auto a, auto b){return a+b;};
auto agg = agg_p(add);
int i;
agg._parse(i);
}
