(Sorry about the delay in responding; I wanted to check behavior on a couple of different systems.) Interesting .... I would have said "isn't a text console a text console, and they all work the same way?" but apparently not -- on one system I use, I get the weird symptom I describe, while on another I don't. I guess it does make a kind of sense given that the two systems have different video hardware and presumably use different drivers. Terminal emulations (gnome-terminal and xterm) seem to be fine on both systems. Setting LC_CTYPE=C on the badly-behaving system makes the annoying symptom go away. I would not have guessed from the description in the gcc man page that this would have any effect on how error messages are formatted. Thanks for the help! -- blm
