In bash-5.2, using the ${parameter@Q} parameter expansion with an unset
parameter, in an array subscript, in an arithmetic context, causes a
segmentation fault.
It seems even ((y[$a])) in arithmetic contexts causes a segfault:
I attach a patch [0001-subst-handle-null-substring.patch].
Thanks for the diagnosis and patch.
