After compiling R-2.6.1 with gcc-4.2.1 pressing the 'delete' key three times in
an interactive session causes R to malfunction, spitting out an infinite stream
of errors.  I have also replicated the issue in R-2.5.1:

You are specifically asked to not report bugs on obsolete versions of R 
and to check for prior similar reports.

R 2.6.2 is the current version.

This has been reported previously (over 2 years ago on R version 2.2.1) 
and was associated with a bug in readline, which is the underlying 
functionality that handles getting input from the user in the console.

Since you are running a 2.4 series kernel, it suggests that you may also 
be running an older Linux distribution.

Be sure that your system is updated, including the readline libraries, 
the current version of which is 5.2.

HTH,
