I can't reproduce that problem:
imadev:~$ unset a; f() { declare -ga a=(1 2); }; f; declare -p a
declare -a a='([0]="1" [1]="2")'

I also can't reproduce it with readonly:
imadev:~$ bash-4.2 -c 'unset a; f() { declare -rga a=(1 2); }; f; declare -p a'
declare -ar a='([0]="1" [1]="2")'

I can't reproduce it that way either:
imadev:~$ f() { declare -ga a=(1 2); }; g() { declare -p a; }; f; g
declare -a a='([0]="1" [1]="2")'
