Bash Version: 2.05
Patch Level: 0
Release Status: release

Description:

There are two Problems:

1.      environment variables are not able to override local function variables
        affects bash2.05

2.      0x1 (Start Of Heading) cannot be passed to a function via $1 (but $@ 
can)
        affects bash2.04, bash2.05


Repeat-By:

consider this function with local variables:
        bash-2.05$ function fff() { local i=0 x=10; echo "|$i|$x|"; }
        bash-2.05$ fff
        |0|10|
        bash-2.05$ x=10 fff
        |0||

bash2.04 reacts as expected:
        bash2.04.0-2.04$ function fff() { local i=0 x=10; echo "|$i|$x|"; }  
        bash2.04.0-2.04$ fff
        |0|10|
        bash2.04.0-2.04$ x=10 fff
        |0|10|

And now consider this function:
        bash-2.05$ function fff() { local i=0 x; x=10; echo "|$i|$x|"; }
        bash-2.05$ fff 
        |0|10|
        bash-2.05$ x=1 fff
        |0|10|

bash2.04:
        bash2.04.0-2.04$ function fff() { local i=0 x; x=10; echo "|$i|$x|"; }
        bash2.04.0-2.04$ fff
        |0|10|
        bash2.04.0-2.04$ x=1 fff
        |0|1|

bash2.05 does not allow to override local variables, it completelely drops the 
local Variable, making the function unable to work correctly.

2.) 
-----------------------------------------------------------------------------

The $# Variable show, in any of these two cases one argument:
        bash-2.05$ function huhu() { echo "$#"; }; huhu $(echo -en "\1")
        1
        bash-2.05$ function huhu() { echo "$#"; }; huhu $(echo -en "\2")
        1

The $@ Variable shows the both Strings correctly:
        bash-2.05$ function huhu() { echo "$@"; }; huhu $(echo -en "\1") | xxd
        0000000: 010a                                     ..
        bash-2.05$ function huhu() { echo "$@"; }; huhu $(echo -en "\2") | xxd
        0000000: 020a                                     ..

But $1 does not:
        bash-2.05$ function huhu() { echo "$1"; }; huhu $(echo -en "\1") | xxd
        0000000: 0a                                       .
        bash-2.05$ function huhu() { echo "$1"; }; huhu $(echo -en "\2") | xxd
        0000000: 020a                                     ..
