           Summary: ICE on member function template specialization
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: stefaandr at hotmail dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu

compiling this code (extracted from bug report 1908): 
struct foo { 
        template<typename T> void bar (T &t) {}; 
        template<> void bar<double>(double &t) {}; 
} 
I get an internal compiler error (suppose it's valid code, but I'm not sure).
