Confirmed. Here's a reduced testcase: 
----------------- 
template <typename T> struct S { 
    typedef int size_type; 
}; 
 
template <typename T> struct C { 
    typedef typename S<T>::size_type size_type; 
 
    size_type foo(); 
}; 
 
template <typename T> 
C<T>::size_type<T> 
C<T>::foo() { return 1; }; 
---------------------------- 
 
The code is invalid (it should read C<T>::size_type, not C<T>::size_type<T>; 
the return type also needs a 'typename') but we ICE anyway: 
 
g/x> /home/bangerth/bin/gcc-3.3.4-pre/bin/c++ -c x.cc 
x.cc:13: internal compiler error: tree check: expected record_type, have  
   typename_type in lookup_template_class, at cp/pt.c:4127 
Please submit a full bug report, 
with preprocessed source if appropriate. 
See <URL:http://gcc.gnu.org/bugs.html> for instructions. 
 
This is not a regression against previous versions, though, and it is fixed 
since 3.4, so I close it as fixed.
