I used to override the local variables in a function.
This works up to version 2.04.
Therefore, your Output is correct.
But the bash2.05 drops the variable completely, if you put a variable 
assignment in front of a function call.

I tested the function on bash2.05a, but the behaviour is like bash2.05

        $ fff() { local i=0 x="${x-10}"; echo "|$i|$x|"; }
        $ fff; x=1 fff; echo "$BASH_VERSION"
        |0|10|
        |0||
        2.05a.0(1)-release
