            Bug ID: 58178
           Summary: variant function name was used for user defined
                    constructor
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: chihin.ko at oracle dot com

test case:
cat t.cc

#include <stdio.h>
struct base {
   int x;
   base() { x= 2;};
};

struct A {
    static int x;
    struct B :base{
        void f() {
            x++;
            printf("x= %d\n",x);
        }
    };
};

 int A::x = 12;

 main()
 {
     A::B z;
     z.f();
 }
/pkg/gnu/bin/g++  -R/pkg/gnu/lib -R/pkg/gnu/lib/amd64 -g t.cc

mandelstam.us.oracle.com 2528> nm a.out | grep base
[95]    | 134548914|        14|FUNC |WEAK |0    |11     |_ZN4baseC2Ev

base class has user defined constructor, I'm expecting _ZN4baseC1Ev from nm

a.out execution does not have problem, it is the debugging support would have
problem.

Thus Solaris (current Linux targets are fine, we know that). Maybe Eric can
have a look.

The configure line for the compiler is needed on Solaris as well.

Confirmed, maybe related to the missing COMDAT support.
