Summary: internal compiler error: in build_over_call, at
cp/call.cc:10918 since gcc 5.5
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mario.rodriguezb1 at um dot es
Target Milestone: ---
ICE on ambiguous, it only happens with Derived3, not any other of Derived
classes:
## Program
```
#include <iostream>
#include <memory>
class Base {
public:
virtual ~Base() = default;
};
class Derived : public virtual Base {};
class Derived2 : public Base {};
class Derived3 : public Derived, Derived2 {};
int main()
{
auto p = std::make_unique<Derived3>();
p->~Base();
return 0;
}
```
