Package: bash Version: 5.2.21-2.1+b1 I have no idea if this is a problem with bash or with readline but for the last week or so, sometimes (fairly often) when I use Ctrl-R to do a history search and recall, it prevents Ctrl-C from working - Ctrl-C is completely ignored, i.e. it doesn't do anything, isn't handled as intr and doesn't even display "^C" on the terminal. There is no response at all to pressing ^C.
To get ^C working again, I have to log out and then log back in again. Or run `exec bash`. Unfortunately, this is not consistent and I have not yet managed to figure out a pattern for when it happens vs when it doesn't happen. BTW I have not changed how I use bash, I have been using ^R for recall in exactly the same way for many years. # dlocate -l '^.i.*(readline|bash)' Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description +++-================-=====================-====================================================== ii bash 5.2.21-2.1+b1:amd64 GNU Bourne Again SHell ii bash-builtins 5.2.21-2.1+b1:amd64 Bash loadable builtins - headers & examples ii libreadline5 5.2+dfsg-3+b13:amd64 GNU readline and history libraries, run-time libraries ii libreadline8t64 8.2-4:amd64 GNU readline and history libraries, run-time libraries ii readline-common 8.2-4:all GNU readline and history libraries, common files stty still indicates that intr is ^C, but it just doesn't work # stty -a speed 38400 baud; rows 61; columns 231; line = 0; intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; discard = ^O; min = 1; time = 0; -parenb -parodd -cmspar cs8 -hupcl -cstopb cread -clocal -crtscts -ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl ixon -ixoff -iuclc -ixany -imaxbel iutf8 opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke -flusho -extproc At first I thought it might be a problem with either /etc/inputrc or ~/.inputrc on one particular machine, but then I noticed it happening on other machines too. AFAICT, there is nothing unusual or wrong about my readling config.
