 Reduced snippet is:
 -----------------------------------------
 struct Bar
 {
     typedef int type;
 };
 
 struct Foo
 {
     void func(void)
     {
         mutable Bar::type x;
     }
 };
 -----------------------------------------
 pr10451.cpp: In member function `void Foo::func()':
 pr10451.cpp:10: Internal compiler error in grokdeclarator, at
 cp/decl.c:11906
 Please submit a full bug report,
 
 The code is illegal, but we should not ICE anyway. This is a 3.2/3.3/3.4
 regression wrt to 2.95 which was giving a normal error message.
 For the original poster: your code is illegal because mutable may not be
 used to define local variables.
