Bash Version: 4.4
Patch Level: 23
Release Status: release
Description:
`history -d` doesn't check for "history position out of range" until
bash returns to prompt
Repeat-By:
find number of last history line: `history|tail -n1`
`history|tail -n4; while history -d $NUM_LAST_LINE; do sleep 0.1; echo
-n .; done`
abort ^C
run again
compare to a single `history -d $(( NUM_LAST_LINE + 1 )); echo $?`
Fix:
bash needs to check for pointer out of range *immediately*
before each `history -d` using the *true* recent length of
internal history list and throw error accordingly
