            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;
}();
