Bug ID: 80427
Summary: DR1658 is implemented in C++03 and C++14 mode, but not
C++11
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: rs2740 at gmail dot com
Target Milestone: ---
Trunk GCC accepts this code given -std=c++03 or -std=c++14:
struct A {
A(int) {};
};
struct B : public virtual A {
virtual void foo() = 0;
};
struct C : public B {
C() : A(1) {}
virtual void foo() {}
};
int main() {
C c;
return 0;
}
but rejects it with -std=c++11.
This doesn't make much sense.
