This could be http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57279. Retry with a new gcc-snapshot when available.

The following code is rejected if compiled with gcc 4.9.0 20130505 (experimental) using the flags

-std=c++11 -Wall -pedantic-errors

//------------------------------------
typedef void fc1() const; // OK
typedef void frr1() &&; // OK
typedef void fcr1() const &;
using fc2 = void() const; // #4
using frr2 = void() &&; // OK
using fcr2 = void() const &; // #6
//------------------------------------

"main.cpp|4|error: invalid qualifiers on non-member function type|
 main.cpp|6|error: invalid qualifiers on non-member function type|"

According to 8.3.5 [dcl.fct] p6 function type declarations with cv-qualifiers are valid via alias-declarations (b3).

[Jason-gcc (jason-gcc)]

Fixed.

[Jakub-gcc (jakub-gcc)]

GCC 4.8.1 has been released.

[Iain Lane (laney)]

Build log. It's for a parallel build; grep for "error:"

[Doko-v (doko-v)]

closing. this apparently did get into the 4.8.1 release. however can't change the milestone back to 4.8.1.

[Matthias Klose (doko)]

fixed upstream in 4.8.1
