[clang] name mangling for lambdas in local classes broken since clang-13 #88906
Description
Minimal Reproducible Example:
#include <iostream>
#include <functional>
int main(){
class Test{
public:
std::function<void()> a{[]{ std::cout << "a\n"; }};
std::function<void()> b{[]{ std::cout << "b\n"; }};
std::function<void()> c{[]{ std::cout << "c\n"; }};
};
Test test{};
test.a();
test.b();
test.c();
}
// output:
c
c
c
// expected:
a
b

So, if you have a local class with lambda's the name mangling seems to be missing/going wrong. Resulting in only one actual lambda being declared.
