Tom just advised me via private e-mail that my termcap database may be the issue here. Looks like he was right. I did a "sudo aptitude reinstall ncurses-base", and now the tests pass against HEAD. (I probably should have tried to preserve things before going ahead with that, but that didn't happen -- I had no reason to think that the system was affected by any kind of corruption.) I am very sorry for having wasted your time on this wild goose chase, Tom. The only explanation I can think of is that maybe it relates to my upgrading the OS in-place. That is, maybe my system was affected by a subtle, low probability bug due to a major version change in ncurses-base. -- Peter Geoghegan
