>Description:
Setting LC_ALL to en_US.UTF-8 will cause bash to crash with the following 
output:

-bash-4.2$ export LC_ALL=en_US.UTF-8 

malloc: unknown:0: assertion botched
free: start and end chunk sizes differ
last command: export LC_ALL=en_US.UTF-8
Aborting...Connection to w.x.y.z closed.

I see the same effect using the following sampled locales:

 - en_CA.UTF-8
 - en_GB.UTF-8
 - zh_TW.UTF-8

Note this *DOES NOT* happen under NetBSD 5.1.2.  This is specific to NetBSD 6.0 
only.


>How-To-Repeat:
Under NetBSD 6.0_BETA2:

 - Set bash options to static in /etc/mk.conf

   PKG_OPTIONS.bash=static

 - Create a user account using bash for the shell
 - Log in as this user
 - set LC_ALL to en_US.UTF-8 (or any unicode locale)

   export LC_ALL=en_US.UTF-8 

 - watch bash crash


>Fix:
Setting the locale to en_US.ISO8859-1 seems to work okay.
