scc.ii

I am getting "Assembler Messages" below from gcc-4.8 when compiling my code.
scc.ii file is attached (original code -- https://github.com/lvv/scc ).  I can
successfully compile if I will use  gcc-3.7.1.

Started in between r189000 and r189400 (r189[123]00 issued errors on it).

pr54538.ii

Reduced testcase for -std=c++11 -O2.  The mangled name doesn't demangle with
c++filt btw.

In r189000 there were two different symbols:
_ZNSt17_Function_handlerIFbRFiSt6vectorIiSaIiEEEENSt11chain_rangeIRS2_E12default_predMUlPS3_E_EE9_M_invokeERKSt9_Any_dataS4_
_ZNSt17_Function_handlerIFbRFiSt6vectorIiSaIiEEEENSt11chain_rangeIOS2_E12default_predMUlPS3_E_EE9_M_invokeERKSt9_Any_dataS4_

one was &, the other &&.
Now they are both:
_ZNSt17_Function_handlerIFbRFiSt6vectorIiSaIiEEEENSt11chain_rangeIT_E12default_predMUlPS3_E_EE9_M_invokeERKSt9_Any_dataS4_
...IRS2_E... vs. ... IOS2_E... vs. ...IT_E...

Incorrect version. It should be 4.7.1

This code is very alpha and not supposed to be compiled with something not GCC.
  CLANG probably will be able to compile it when they will fix constexpr bug
11851  ( http://llvm.org/bugs/show_bug.cgi?id=11851).  Don't know about ICC or
how it supports C++11. 

Assembler messeges were not from unit test, but from this:

It seams that gcc bugzilla substituted text "bug some-number" with erroneous
link.
