 Hi,
 
 here's a little cleaned-up testcase:
 
 --------------------------------snip here-----------------------------
 template <typename T> struct A {};
 
 template <typename T> struct B
 {
     template <typename U> struct C {};
     template <typename U> A<C<U> > foo(U);
 };
 
 B<void> b;
 --------------------------------snip here-----------------------------
 
 With gcc 2.95.x and gcc 3.0.x the code compiles fine. With mainline
 we get the following ICE
 
 PR8442.cc: In instantiation of `B<void>':
 PR8442.cc:9:   instantiated from here
 PR8442.cc:6: error: type/value mismatch at argument 1 in template parameter 
    list for `template<class T> struct A'
 PR8442.cc:6: error:   expected a type, got `C'
 PR8442.cc:6: internal compiler error: tree check: expected var_decl, have 
    error_mark in tsubst_decl, at cp/pt.c:5793
 Please submit a full bug report, [etc.]
 
 which is replaced by an "confused by earlier errors" on the 3.2 branch
 (checked on i686-pc-linux-gnu and mips-sgi-irix6.5).
 
 Since this a regression, I rated the PR "high priority".
 
 Greetings,
 Volker
