Bash Version: 5.2
Patch Level: 15
Release Status: release
Description:
The handling of EOF while parsing an (unmatched) quoted string changes
between 5.1 and 5.2. In 5.1, typing [Ctrl-d] alone while in the context of
a quoted string in an interactive shell will report a syntax error, and
prompt for a new command. In 5.2, the same action does not report a syntax
error, and instead the shell exits.
The shell should exit on EOF. Previous versions relied on undocumented
bison behavior, which resulted in a token that wasn't handled by the
grammar.
If there's a bug here, it's that interactive shells need to handle
IGNOREEOF in this case.
