strange problem with local bash build -> [a-z] matches A

[Quentin Fennessy]

I am puzzled with a problem we've found locally. We have bash 2.02 built for
and on Linux and Solaris 2.5.1. When run on certain Solaris 7 systems the
[a-z] pattern matching works incorrectly. When a copy of the same bash is run
on other Solaris 7 systems it works correctly. This is how failure looks:

 OS        Bash version      works/fails?
 --        ------------      ------------
 Linux2.2  2.02              fails
 Linux2.2  2.03              fails

 Sol2.5    2.02              works
 Sol2.7    2.03              fails sometimes, works others
 

    $ mkdir tmp
    $ cd tmp
    $ touch A
    $ echo [a-z]
    [a-z]

    $ touch B
    $ echo [a-z]
    B

    $ set|grep BASH
    BASH=/tool/pandora/bin/bash
    BASH_VERSINFO=([0]="2" 
                   [1]="02" 
                   [2]="1" 
                   [3]="1" 
                   [4]="release" 
                   [5]="sparc-sun-solaris2.5.1")
    BASH_VERSION='2.02.1(1)-release'

    $ shopt | grep glob
    dotglob         off
    extglob         off
    nocaseglob      off
    nullglob        off

The strangest part is that [a-z] works on some SOlaris 2.7 systems and fails
on others. I have not been able to figure out what the important difference
is between the two systems.

I cannot find a system dependency in the bash source code that corresponds
to the [a-z] capability. What am I missing?

Thanks.
