Bug ID: 109114
Summary: lambdas should be non-pod for ABI
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: dblaikie at gmail dot com
Target Milestone: ---
See original bug filed against clang:
https://github.com/llvm/llvm-project/issues/59078
itanium-cxx-abi bug: https://github.com/itanium-cxx-abi/cxx-abi/issues/156
(inverted, so it fails with GCC and passes with Clang) example from the clang
bug: https://godbolt.org/z/45TxsPehe
```
template <typename ...T>
struct Callables : T ... {
Callables(T ...t) : T(t) ... {}
using T::operator() ...;
};
inline auto f(int x, char y) {
Callables callables([x, y](void) {}, [y](int) {});
static_assert(sizeof(callables) == 8);
return callables;
}
int main(void) { f(0, 1)(42); }
```
Maybe still an open question about lambdas that don't capture - since they do
have a default ctor, but the spec still says they're non-aggregate.
