Bug ID: 66108
Summary: cv-qualification deducation failure on conversion
operator
Product: gcc
Version: 5.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: barry.revzin at gmail dot com
Target Milestone: ---
Consider this code (taken from SO question)
#include <iostream>
struct A {
template <class T> operator T***()
{
static_assert(std::is_same<T, int>::value, "oops");
}
};
int main(){
A a;
const int * const * const * p1 = a;
}
This is exactly the example taken from the standard in [temp.deduct.conv]/7,
yet on gcc 5.1, the static assertion fails because T is deduced as const int
rather than int.
