Title:
bash: non existent locale crashes bash
Status in bash package in Ubuntu:
Fix Committed
Status in bash package in Debian:
New
Bug description:
Imported from Debian bug http://bugs.debian.org/1021109:
Package: libc6
Version: 2.35-1
Severity: grave
Justification: renders package unusable
X-Debbugs-Cc: kos...@debian.org
Dear maintainer,
After upgrading to libc6 2.35-1 (or 2.36-1 in experimental), nonexistent
locale setting
starts to crash the system.
This is dangerous because a remote system might not always have the same
locale installed.
An auto update will soft-brick the system unless the sysadmin knows to set
their LC_ALL=POSIX
before attempting to ssh.
Steps to reproduce:
From a clean installed Debian sid, upgrade to libc6 2.35-1.
Only install C locale and en_US.UTF-8.
$ LC_ALL=ja_JP.UTF-8 bash
bash: warning: setlocale: LC_ALL: cannot change locale (ja_JP.UTF-8)
Segmentation fault (core dumped)
$ LC_ALL=ja_JP.UTF-8 gdb bash
Fatal signal: Segmentation fault
----- Backtrace -----

0x7f0b4b4122f1 _rl_init_eightbit
0x7f0b4b3f10f2 rl_initialize
... snip ...
Downgrade to 2.34-8 seems also don't fix the issue, probably some locale
state was invalidated when upgrading.
Thanks,
Kan-Ru
