            Bug ID: 58566
           Summary: [c++0x] ICE with invalid expression in lambda body
           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 4.8.0:

=================================
struct A
{
  int foo()
  {
    [this]{ return foo; };
  }
};
=================================

bug.cc: In lambda function:
bug.cc:5:25: error: invalid use of member function (did you forget the '()' ?)
     [this]{ return foo; };
                         ^
