This also fails with the C++ front-end:
int __attribute__((access("+nosimd"))) rdonly_v_all();

--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
/* This is a request to merge an internal specification for
a function declaration involving arrays but no explicit
attribute access. */
tree vblist = TREE_CHAIN (args);
tree axstr = append_access_attr (node, attrs, NULL, str + 1,
vblist);
if (!axstr)
return NULL_TREE;
Should the front-end do the checking to make what is after the + is valid or
should append_access_attr ?
