Bash Version: 3.2
Patch Level: 33
Release Status: release

Description:
        On newer versions of NetBSD (seemingly anything v.3 or above), attempts
to use any of the wildcards '*', '?', and '[' ... ']' (though not '{' ... '}')
result in bash suddenly terminating & creating a core image, having received
"signal 12."  This happens regardless of the number of matches and regardless
of whether there are any matches at all.  Interestingly, if the 'failglob'
option is set, bash prints a message about being unable to find any matches
(even if there were matches) before terminating.  This bug has only been
observed in the version of bash specified above.

Sorry, I can't reproduce this on any of my systems.

Chet
