I tried to submit this in R, but not sure if it worked. When running R as sudo, using ctrl-c dumps me to the command line. Hitting exit to exit the terminal window results in R taking 100% of resources. I am using R-2.1.0 on Fedora Core 3. Thanks. Manuel
I suspect that we are going to need more information. Running on a fully updated FC3 box using Xfce's Terminal, gnome-terminal and kconsole, I cannot duplicate this issue either as a user or as root using sudo.
Note that this doesn't happen if I run R as a normal user or as root. I.e., R <ctrl-c> or su R <ctrl-c> works fine. sudo R <ctrl-c> does not.

Was there a program running in R at the time, or were you at the R prompt when you hit ctrl-c?
R prompt
Which desktop environment and terminal emulator are you using?
Gnome and gnome-terminal, although the problem also happens when using xterm.
Have you perhaps re-mapped ctrl-c using modified keybindings?
No. And ctrl-c works fine as a normal user or as root.
Manuel, Please be sure to copy R-bugs@biostat.ku.dk when you reply so that the thread is properly archived in the bug tracking system. I tried this under GNOME using gnome-terminal and the unpatched version of R 2.1.0 and still could not duplicate the problem. Can you post back with the contents of /etc/sudoers? The other possibility would be to run: sudo R -d gdb in gnome-terminal. When you get to the (gdb) prompt, type 'r' (without the quotes) for run, which will start up R. If you can replicate the problem under gdb and R exits after a ctrl-c, you should be left at a (gdb) prompt. If that occurs, type 'bt' (without the quotes), which will display a backtrace. If that all works, post the output of gdb from the crtl-c through and including the backtrace here. Marc
