             Bug #: 55032
           Summary: [4.7 Regression] Internal compiler error: in
                    strip_typedefs, at cp/tree.c:1199
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: bruno-gcc@defraine.net


Some variations of bug #53989 still seem to exist (or gcc 4.7.2 does not
contain a complete fix for that bug).

$ cat Test.cpp
template<typename T>
struct vec3t {
  T c[3];
};

typedef vec3t<float> vec3;

class Bounds {
  public:
    Bounds(const vec3 bb[2]);
    void foo(const vec3 & v) { v.c[0]; }
};

template<typename T>
void work(T& value);

void foo() {
  vec3 bb[2];
  work(bb);
}

$ g++ -Wall -c Test.cpp
Test.cpp: In member function 'void Bounds::foo(const vec3&)':
Test.cpp:11:38: warning: statement has no effect [-Wunused-value]
Test.cpp: In function 'void foo()':
Test.cpp:19:10: internal compiler error: in strip_typedefs, at cp/tree.c:1199
