Bug ID: 114267
Summary: bogus -Wsubobject-linkage when using lambda members as
template parameters
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: brunopitrus at hotmail dot com
Target Milestone: ---
header.h:
```
struct F{
constexpr static const auto algorithm=[]() {};
};
constexpr inline const auto algorithm=[]() {};
template<auto algo> struct G{};
struct S{
G<algorithm> foo; //ok
G<F::algorithm> lol; //Wsubobject-linkage
};
```
main.cpp:
//can be empty
See it on godbolt:
https://godbolt.org/z/qccjfTPnr
The behavior is inconsistent between the lambda declared as a member and as a
non-member. Moreover, if i compile this code with -O0, the resultant object has
a ‘r’ private symbol for F::algorithm, which makes me suspect that wrong code
is being generated.
