It looks like it can easily be fixed with this:

diff --git a/subst.c b/subst.c
index 4f12f22d..cc9a6803 100644
--- a/subst.c
+++ b/subst.c
@@ -9245,7 +9245,13 @@ parameter_brace_expand (string, indexp, quoted,

     }

-  if (valid_array_reference (name, 0))
+  if (want_indir)
+    {

+    all_element_arrayref = 1;

+  else if (valid_array_reference (name, 0))
     {
       int qflags;
       char *t;
