        * ipa.c (symbol_table::remove_unreachable_nodes): Mark all inline
clones
        as having abstract origin used.
        * ipa-inline-transform.c (can_remove_node_now_p_1): Drop abstract
origin check.
        (clone_inlined_nodes): Copy abstract originflag.
        * lto-cgraph.c (compute_ltrans_boundary): Use get_create to get
abstract origin node.

This is a tree sharing issue, it reproduces with -O3 and a single concatenated

I can confirm that the patch can compile all Chromium source files
(unfortunately I hit another issued during LINK phase: PR64583).

Apart from that, both testcases from this issue and PR64559 work (I prepared
patch which installs these testcases).

I run regression tests for c,c++ and no new regression is introduced.

Hello-

I ran into the same error message as below while compiling for m32c
('error: unable to find a register to spill in class 'A_REGS'')

I applied the patches provided in Comment 5

Now the build succeeds.  Cannot test code coming out of the build, though.

I can't reproduce your claim about 4.8.  This warns for me with all compilers
I've tried back from 4.0 till latest trunk, including 4.8 and many others.

            Bug ID: 64615
           Summary: Access level check error: g++ thinks the non default
                    ctor is protected while its public
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: petschy at gmail dot com

Access level is changed from protected (base class) to public (derived class)
via using declaration. The default ctor and the two overloaded member functions
are accessible, however the non-default ctor is not, g++ complains that it's
protected.

g++ 4.9 and 5.0 (20150115) give the same error messages.
cmdline:
g++-5.0.0 -Wall -std=c++11 20150115-using_base_ctor.cpp

----8<---8<---8<---8<---
class B
{
protected:
        B() { }
        B(int) { }
        void Foo() { }
        void Foo(int) { }
};
class D : public B
{
public:
        using B::B;
        using B::Foo;
};
void d_ctor()
{
        D d;
}
void d_ctor2()
{
        D d(0); // !
}
void d_foo(D* d)
{
        d->Foo();
}
void d_foo2(D* d)
{
        d->Foo(0);
}
