What I mean is that we consistently see this behavior across all of our systems, which are all running identical software, including gdb 7.8.1. This probably isn't surprising :) I should also mention that we're running gdb as root. Not sure if that matters. I'm not familiar with inputrc, unfortunately. Can you tell me if there's anything weird in there? I have nothing in ~root/.inputrc, but here's the contents of /etc/inputrc: # /etc/inputrc - global inputrc for libreadline # See readline(3readline) and `info rluserman' for more information. # Be 8 bit clean. set input-meta on set output-meta on # To allow the use of 8bit-characters like the german umlauts, comment out # the line below.
