             Bug #: 53989
           Summary: Internal compiler error in strip_typedefs, at
                    cp/tree.c:1187
    Classification: Unclassified
           Product: gcc
           Version: 4.7.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: gcc@limax.org


Running 'g++ -std=c++0x -c test.cpp' with the following source saved as
test.cpp:

---------------
struct Foo {
  int value;
  static Foo const foos[2];
};

void bar() {
  for (Foo f : Foo::foos) { (void) f; }
}
--------------

produces this result:

---------------
test.cpp: In function âvoid bar()â:
test.cpp:8:21: internal compiler error: in strip_typedefs, at cp/tree.c:1187
---------------


If I get rid of the 'value' member of Foo, or if I provide a definition of
Foo::foos before it is used by Bar, or if I change Foo::foos to be type 'Foo'
instead of type 'Foo const', or if I move Foo::foos outside of class Foo, I
don't see the error.
