11 Bug-Description:
12
13 Bash-4.2 does not attempt to save the shell history on receipt of a
14 terminating signal that is handled synchronously.  Unfortunately, the
15 `close' button on most X11 terminal emulators sends SIGHUP, which
16 kills the shell.
17
18 This is a very small patch to save the history in the case that an
19 interactive shell receives a SIGHUP or SIGTERM while in readline and
20 reading a command.
21
22 The next version of bash will do this differently.
