Bug ID: 110486
Summary: gcc rejects constant expression with consteval lambda
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: hewillk at gmail dot com
Target Milestone: ---
GCC rejects the following, while MSVC and Clang compile fine.
Not sure if the code is well-formed.
#include <vector>
constexpr auto g = []() consteval {
std::vector<int> v;
v.push_back(0);
return v;
};
constexpr auto l = [] {
constexpr auto sz = g().size();
return 0;
}();

If it is, then the bug is dealing with that. That is adding consteval to the second lamdba allows GCC to accept the code. ^ permalink raw reply [flat|nested] 3+ messages in thread
