The following reply was made to PR debug/8384; it has been noted by GNATS.

 Here's a shorter example:
 --------------------------------
 int foo;
 
 template <class T> struct Base  {
   typedef  T  type;
 };
 
 template<class T>
 struct Derived : public Base<typeof(foo)> {};
 -------------------------------
 
 Message is:
 -------------------------------
 tmp/g> /home/bangerth/bin/gcc-3.3-pre/bin/c++ -g x.cc
 x.cc: In instantiation of `Base<__typeof (foo)>':
 x.cc:8:   instantiated from here
 x.cc:3: internal compiler error: in is_base_type, at dwarf2out.c:7477
 Please submit a full bug report,
 with preprocessed source if appropriate.
 See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
 -------------------------------
 
 I believe that if this problem is fixed, the code will still not compile 
 but the next issue will then be c++/8385.
 
 Regards
   Wolfgang

Old Synopsis: g++ -g  gives ICE, but compiles ok without -g
New Synopsis: ICE in is_base_type, at dwarf2out.c:7477

    2.95 used to say:

    x.cc:14: confused by earlier errors, bailing out
    
    
    3.2 and present CVS say this:
    x.cc: In instantiation of `Identity<__typeof ((true ? fakemake<T>() : fakemake<U>()))>':
