Subject: bash: 'read -e -t 1' triggers bash exit

Date: Thu, 10 Nov 2022 01:36:01 +0100

Package: bash
Version: 5.2-2+b1
Severity: important

Dear Maintainer,

Since Bash 5.2, when both -e and -t options are used, read terminates the shell session.

This can be tested as follow in a terminal:

> /usr/bin/bash
> echo $SHLVL
2
> read -e -t 1
> echo $SHLVL
1

or by executing this small script where any subsequent use of read -e is rendered ineffective:

#!/usr/bin/env bash
read -et .001
read -e -p "type something: "
echo -e "\nyou typed $REPLY"


Note that 'read -e -t 0' does not exit, so it really has something to do with timings.

Regards,
Fabien
