<pre>The code is as follow:
template <int>
int f(void)
{
int i;
struct f1
{
int f(void){return i;}
};
}
Clang++ accepts the code, but g++ rejects it:
code0.cpp: In member function 'int f()::f1::f()':
code0.cpp:7:21: error: use of local variable with automatic storage from
containing function
int f(void){return i;}
^
code0.cpp:4:6: note: 'int i' declared here
int i;
^
code0.cpp: In function 'int f()':
code0.cpp:9:1: warning: no return statement in function returning non-void
[-Wreturn-type]
}
^</pre>
