           Summary: [4.7 Regression] ICE in build_new_method_call
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: redi@gcc.gnu.org


#include <functional>
#include <chrono>
#include <memory>
#include <condition_variable>

struct Impl;
typedef std::shared_ptr<Impl> shared_base_type;

struct base
{
  shared_base_type ptr;
};

struct Impl : base
{
  Impl() = default;
};


The c++0x code above gives me an ICE with trunk, but it goes away if I change
any of the includes, or try to compile a preprocessed version (which is why I
haven't attached preprocessed source)

$  ~/gcc/4.x/bin/g++ -std=c++0x ice.cc -c 
ice.cc:14:8: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.

I'm able to reproduce this on two different machines with trunk so I don't
think it's just something weird on my machine - can anyone else reproduce it?

Jon, I can, sadly.

Thanks, Paolo.  I'm not sure how to reduce it further, the only header that's
needed is <memory> but removing the others prevents the ICE

No, I can't either with current trunk

Unless Paolo can still reproduce it I guess we can close it as WORKSFORME

Can't reproduce anymore either.
