            Bug ID: 30364
           Summary: wrong __PRETTY_FUNCTION__ found, from the wrong scope
           Product: clang
           Version: 3.9
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: marmoo1024 at gmail.com

    Classification: Unclassified

For the following code produces a warning, and s is initialized from outside
the function.

#include <stdio.h>
void function() {
    struct obj {
       const char * str;
       obj(const char * s = __PRETTY_FUNCTION__ /*or __func__*/)
        : str(s) {};
    };
    printf ("%s\n",obj().str);
}
int main () {function();}

__func__ and __PRETTY_FUNCTION__ are supposed to be static const char *,
so they should be visible. Instead in 3.9 "top level" is printed. 

If __PRETTY_FUNCTION__ is replaced with a static variable, an error is produced
instead. 

#include <stdio.h>
const char other[] = "other";

void function() {
    static const char other[] = "other";
    struct obj {
        const char * str;
        obj(const char * s=other)
        : str(s){};
    };
    printf ("%s\n",obj().str);
}

int main () {function();}
