            Bug ID: 58581
           Summary: [4.7/4.8/4.9 Regression] [c++11] ICE with no-throw
                    specification in deleted function
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: reichelt at gcc dot gnu.org

The following invalid code snippet (compiled with "std=c++0x") triggers an ICE
since GCC 4.7.0:

===========================================================
template<typename T> int foo(T) noexcept(T()) = delete;

int i = foo(0);
===========================================================
