Bug ID: 61471
Summary: redeclaration of default-argument in function template
declaration not caught
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org

testcase.cpp
template<class T> void f(int=3);
template<class T> void f(int=3); // ill-formed
int main () { }
------------------------
`gcc` inaccurately accepts the above snippet, which is violating the following
[dcl.fct.default]p4:
> A default argument shall not be redefined b a later declaration
> (not even to the same value).
------------------------
By making `f` a non-template the violating is caught, and appropriate
diagnostics are shown.
