Hi! In my Alpha(ev56) Linux box (with RH6.1, gcc 2.95.2, the latest GiNaC from CVS, CLN-1.1, GMP-3.1.1) the lt-exams test is running already 15 hours: <snip> GiNaC will now take an exam with specific input (like a pupils' exam): examining several historic failures just out of paranoia.......... Any ideas why? Pearu
