The attached patch seems to take care of at least these two cases:

|  address@hidden ...src/gnu/bash % ./bash --norc --noprofile -c 'r=@; declare 
-n r'
|  ./bash: line 0: declare: @: invalid variable name for name reference
|  
|  address@hidden ...src/gnu/bash % ./bash --norc --noprofile -c 'declare -n r; 
r=@'
|  ./bash: `@': not a valid identifier
|  
|  address@hidden ...src/gnu/bash % ./bash --norc --noprofile -c 'declare -n r; 
r=$(echo @)'
|  ./bash: `@': not a valid identifier

But I think Chet already considered this, given that the check in declare.def
was '#if 0'ed out.
