 The regression reported in PR c++/8572 showed up starting with this
 patch, which might merely uncover an existing problem:
 
 2002-03-20  Nathan Sidwell  <nathan@codesourcery.com>
 
         PR c++/4361
         * mangle.c (struct globals) Add internal_mangling_p member.
         (write_template_param): Do internal mangling, if needed.
         (mangle_conv_op_name_for_type): Request internal mangling.
 
 Here's a small test case that causes the ICE, which occurs in the
 mainline but not in the 3.2 branch:
 
 ---------------
 template <typename T> struct A
 {
   struct B { B() {} };
   operator B* () const;
 };
 
 template <typename T> A<T>::operator typename A<T>::B*() const { return
 0;
 }
 ---------------
 
 Compiler output from the mainline with this test:
 
 8572.C:7: internal compiler error: in mangle_conv_op_name_for_type, at
    cp/mangle.c:2612
