            Bug ID: 58647
           Summary: [4.7/4.8/4.9 Regression] ICE with function pointer
           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 valid code snippet triggers an ICE since GCC 4.7.0 only if
compiled with "-std=c++11". Without this option the code compiles fine.

======================================
struct A
{
  static void foo();
};

template<typename> void bar()
{
  A().foo;
}
======================================

bug.cc: In function 'void bar()':
bug.cc:8:10: internal compiler error: tree check: expected tree that contains
'decl common' structure, have 'baselink' in cxx_eval_component_reference, at
cp/semantics.c:7145
