'declare +a -g' destroys local arrays

[Arfrever Frehtes Taifersar Arahesis]

I use bash 4.2.45.

`man bash` says:
"Using `+' instead of `-' turns off the attribute instead, with the exceptions 
that +a may not be
used to destroy an array variable and +r will not remove the readonly 
attribute."

However 'declare +a -g' destroys local arrays, which do not shadow global 
arrays:

$ f() { local ARRAY=(a b c); declare -p ARRAY; declare +a -g ARRAY; declare -p 
ARRAY; }
$ f
declare -a ARRAY='([0]="a" [1]="b" [2]="c")'
bash: declare: ARRAY: cannot destroy array variables in this way
bash: declare: ARRAY: not found
$ ARRAY=(x y z)
$ f
declare -a ARRAY='([0]="a" [1]="b" [2]="c")'
bash: declare: ARRAY: cannot destroy array variables in this way
declare -a ARRAY='([0]="a" [1]="b" [2]="c")'
