           Summary: ICE with initializer_list of unique_ptr in gcc-4.6.0
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: john.salmon@deshaw.com


The following code generates an ICE while trying to create a
std::initializer_list of unique_ptrs.  This is with
Target=x86_64-unknown-linux-gnu.

salmonj@drdlogin0039.en.desres$ cat il.cpp
#include <memory>

struct Foo{
    int i;
};
typedef std::unique_ptr<Foo> up;

std::initializer_list<up> il{up{new Foo}, up{new Foo}};

salmonj@drdlogin0039.en.desres$ desres-cleanenv -m gcc/4.6.0-23A/bin g++
-std=c++0x -Wall -c -o il.o il.cpp
il.cpp:8:55: internal compiler error: in record_reference, at cgraphbuild.c:60

if this is PR 48281 then it's fixed in 4.6.1

Maybe it isn't? Because I just rebuilt 4_6-branch (Rev. 172860) and still ICEs
for me. Mainline is fine, however.

Let's mark it as a regression too, to play safe.

It was fixed on the trunk by the last patch I posted with the fix for 48281,
which I've now applied for 4.6.1 as well.
