Bug ID: 99611
Summary: Code compilation issue using templates
Product: gcc
Version: 9.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: asif_bahrainwala at hotmail dot com
Target Milestone: ---
Hi,
a minimalist re-pro is available at
https://stackoverflow.com/questions/66641646/c-code-compilation-usage-of-fstream-ostream
The below code compiles in Clang but not in GCC (and VS2015):
#include <iostream>
#include <fstream>
using namespace std;
struct A
{
int z=0;
template<typename T>
void func(T &y)
{
//cout<<typeid(T).name()<<endl;
y<<z<<endl;
}
};
template<typename T,typename T1>
T& operator<<(T &y,T1 &y1)
{
y1.func(y);
return y;
}
int main()
{
A a;
a.z=10;
fstream fs("a.txt",ios::out);
fs<<a; //this doesnt compile ???? ( I do have a walk around, but curious)
cout<<a; //this works
return 0;
}

Thanks for the bug report. This looks like a dup of PR51577, which has
recently been partially fixed on trunk.
*** This bug has been marked as a duplicate of bug 51577 ***
