             Bug #: 54198
           Summary: [4.8 Regression]  "error: invalid use of incomplete
                    type" when building Chromium
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: markus@trippelsdorf.de


Chromium (22.0.1229.0) fails to build with current gcc trunk:

The testcase is too big to attach (416KB bziped).

I've reduced it with C-reduce:

markus@x4 tmp % cat test.ii
template <typename T> void
refIfNotNull (T* p1)
{
    p1->ref;
}
template <typename T> struct A
{
    A (T* p1)
    {
        refIfNotNull (p1);
    }
};
class B;
class C
{
    void getParent (A <B> = 0);
};

markus@x4 tmp % g++ -c test.ii
test.ii: In instantiation of ‘void refIfNotNull(T*) [with T = B]’:
test.ii:10:9:   required from ‘A<T>::A(T*) [with T = B]’
test.ii:16:29:   required from here
test.ii:4:5: error: invalid use of incomplete type ‘class B’
     p1->ref;
     ^
test.ii:13:7: error: forward declaration of ‘class B’
 class B;
       ^

        * cp-tree.h (tsubst_flags): Remove tf_no_access_control.
        * call.c (standard_conversion): Don't set it.
        * class.c (resolve_address_of_overloaded_function): Don't check it.
        * decl.c (check_default_argument): Call
        perform_implicit_conversion_flags.

Clang++ and Intel's icpc compile the testcase without problems.

I actually think GCC is correct, A <B> causes all member functions to be
instantiated.

(In reply to comment #2)

> instantiated.

I disagree, the instantiation of A<B> shall only instantiate all member
*declarations*, but not the *definitions* of unused members.
