Bash Version: 3.1
Patch Level: 11
Release Status: release

Description:
I've found some of my old scripts result in a syntax error. I 
don't know if it's an error in the parser, the scripts or the bash 
options.

Repeat-By:
This fails in 3.1x but in 3.0x:

sh-3.1$ let HI=(16-10)/2
sh: let: /2: syntax error: operand expected (error token is 
"/2")

This works:

sh-3.1$ ((HOLA=(16-10)/2))

--

This fails in 3.1x but in 3.0x:

sh-3.1$ for i in 1 2 3; do echo ${TOKEN["$i"]}; done
sh: "1": syntax error: operand expected (error token is ""1"")

This works:

sh-3.1$ for i in 1 2 3; do echo ${TOKEN[$i]}; done

$* and $@ broken on some (64 bit?) platforms in bash 3.1

Bash Version: 3.1
Patch Level: 14
Release Status: release

Description:
$* and $@ show $1 (or $2, only on DEC Alpha) instead of " " (space) as 
separator of arguments.

I've tried both bash 3.1 patch level 5 and 14 on Mac OS X, no difference. 

bash 3.00.16(2)-release does not show this bug! 


Repeat-By:

./mactest.sh x y z
xxyxz
xxyxz
xxyxz
arg1 = x
arg2 = y

with the following script:

 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< 
#!/usr/local/bin/bash

echo $*
echo $@
echo "$@"

echo "arg1 = $1"
echo "arg2 = $2"
 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< 

further testing on other platforms show the patterns below,
so it looks like being a problem on some 64 bit platforms, but not 
on x86_64 (running SUSE 9.0).  
we're using gcc-3.3.3 or gcc-3.3.4 for building on those platforms.
