Details:

dev octave fails to instantiate a classdef, that has a property that is
initialized to another classdef. See below for how to reproduce, and the
octave-5.0.91 and octave-6.0.0 outputs. Apparently the pckg package name in
the pckg.cls2 invocation is not recognized as a package, but interpreted as a
string.

file lay-out


./use_pckg.m
./+pckg/cls1.m
./+pckg/cls2.m



classdef cls1
  properties
    c2 = pckg.cls2;
  end
end



classdef cls2
end



% script use_pckg
ver = version
hg_id = __octave_config_info__.hg_id
addpath(pwd);
cls1_inst = pckg.cls1


octave-5.0.x output:


ver = 5.0.91
hg_id = b812ed975ea8+
cls1_inst =
<object pckg.cls1>


octave 6.0.0 output:


ver = 6.0.0
hg_id = 568565a70b58+
error: sq_string cannot be indexed with .
error: called from
    use_pckg at line 5 column 11
