Package: gdb
Version: 7.8.1-1
gdb in batch mode leaves the terminal in a broken state. To reproduce,
run this:
gdb -batch -ex 'run hello world' echo
Strace tells me that gdb disables echo and canonical mode, but never
restores the terminal attributes:
$ strace -e ioctl -o '| grep -w TCSETSW' gdb -batch -ex 'run hello world' echo
hello world
[Inferior 1 (process 596) exited normally]
ioctl(0, SNDCTL_TMR_STOP or SNDRV_TIMER_IOCTL_GINFO or TCSETSW, {B38400 opost
isig -icanon -echo ...}) = 0
Work-around: redirect gdb's stdin to /dev/null.
