C++, 2.95: ICE with ?: operator

[Wolfgang Bangerth <wolf at gaia dot iwr dot uni-heidelberg dot de>]

// This strange bit of code produces an ICE.
// Configuration:
//    gcc version 2.95 19990728 (release)
//    sparc-sun-solaris2.6
//
// gcc output:
//     tmp/x> c++ -c a.cc
//     a.cc: In method `void Outer::test()':
//     a.cc:41: Internal compiler error 364.
//     a.cc:41: Please submit a full bug report to
`egcs-bugs@egcs.cygnus.com'.
//     a.cc:41: See <URL:http://egcs.cygnus.com/faq.html#bugreport> for
details.
//     
// Notes:
//  - first casting inner_[12] to (Base&) solves the problem and needs
//    indeed be done, if I understand the standard right
//  - the "template<>" is commented out since it is not accepted (see
//    my previous mail)
// Best regards,
//   Wolfgang
