With some debugging:

# prove --blib t/1.simple.t
t/1.simple.t .. 1/1 
#   Failed test at t/1.simple.t line 23.
#          got: 'digraph test {

#   edge [color=black];
#   graph [bb="0,0,0,0"];

#   Dr [label=Dr, pos="0,0", width="0.0", height="0.0"];
#   Crude [label=Crude, pos="0,0", width="0.0", height="0.0"];
#   Alice [label=Alice, pos="0,0", width="0.0", height="0.0"];

#     expected: 'digraph test {

Failed 1/1 subtests 

Hash randomization at work somewhere? Next try:

# prove --blib t/1.simple.t
t/1.simple.t .. 1/1 
#   Failed test at t/1.simple.t line 23.
#          got: 'digraph test {

#   Alice [label=Alice, pos="0,0", width="0.0", height="0.0"];
#   Dr [label=Dr, pos="0,0", width="0.0", height="0.0"];
#   Bob [label=Bob, pos="0,0", width="0.0", height="0.0"];
#   Crude [label=Crude, pos="0,0", width="0.0", height="0.0"];
# }
# '
#     expected: 'digraph test {

#   graph [bb="0,0,0,0"];

# Looks like you failed 1 test of 1.
t/1.simple.t .. Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/1 subtests 

Yup, the order changes again.

Maybe caused by libgraph-perl ...?

The $g (Graph object) in t/1.simple.t looks like:

bless( [
#   0,
#   4,
#   bless( [
#     4,
#     152,
#     1,
#     {
#       '0' => 'Alice',
#       '1' => 'Bob',
#       '2' => 'Crude',
#       '3' => 'Dr'
#     },
#     {
#       'Alice' => 0,
#       'Bob' => 1,
#       'Crude' => 2,
#       'Dr' => 3
#     },
#     {},
#     $VAR1
#   ], 'Graph::AdjacencyMap::Light' ),
#   bless( [
#     0,
#     128,
#     2,
#     {},
#     {},
#     {},
#     $VAR1
#   ], 'Graph::AdjacencyMap::Light' )
# ], 'Graph' )



Forwarding the bug upstream now ...


Cheers,
