Bug ID: 69924
Summary: gcc5.2 compile Error: std::basic_istream: no match for
'operator>>', while gcc 4.8 works
Product: gcc
Version: 5.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: derrick at ca dot ibm.com
Target Milestone: ---
For the following code, it compiles successfully on gcc 4.8, but fails on gcc
5.2
#include <iostream>
#include <locale>
inline int operator<<(void*, const std::locale&) { return 1; }
inline int operator>>(void*, const std::locale&) { return 1; }
inline int operator<<(bool, const std::locale&) { return 2; }
inline int operator>>(bool, const std::locale&) { return 2; }
int main(int argc, char *argv[])
{
std::locale loc;
if((std::cin >> loc)!=1)
return 1;
if((std::cout << loc)!=1);
return 1;
return 0;
}
error: no match for 'operator>>' (operand types are 'std::istream {aka
std::basic_istream<char>}' and 'std::locale')
if((std::cin >> loc)!=1)
error: cannot bind 'std::istream {aka std::basic_istream<char>}' lvalue to
'std::basic_istream<char>&&'
if((std::cin >> loc)!=1)
