Brief answer: `-a'
Less brief answer: (0, 4, 3, 1, 2)
Readable answer:
In the canonical order, the first pair of images already does
*not* overlap and Enblend issues a (deserved) warning. Re-order the
images e.g. as (0, 4, 3, 1, 2) or stick with the canonical order and
pass the pre-assemble option `-a'.
The behavior you experience is expected as Enblend's algorithm adds
one image after the other, blending each with the *result* of all
images before. This is described in the user manual.
I prepared a set of patches that
(1) Give pre-assembling a more prominent position by adding long
forms `--pre-assemble' and `--no-pre-assemble'.
(2) Exploit more parallelism in the pre-assembly code path.
(3) Give a more descriptive warning when encountering
non-overlaps.
Please contact me by email if you are interested in alpha-testing
these patches.
If we let us guide by the principle-of-least-surprise, even a program
abort is conceivable in case (3). What do you think?
As you are an extraordinarily experienced user of Enblend and a native
speaker of English (one excuse less, he he!) you are cordially invited
to improve on the Enblend user manual to further clarify the default
`one-by-one' and `pre-assemble' variants.

Title:
Blending error
Status in Enblend:
New
Bug description:
Using test images supplied by Hans Bull, I get a blending error using Enblend
4.2.0 (1116:fd5bc9fbf096).
The blending error does not occur with Multiblend.
This error appears to be particularly sensitive to the crop boundary. I have
not been able to reproduce the error for any other settings than those in the
.pto file.
Attached images, .pto and resulting stitch.
I am using Fedora 20 x86_64 hugin-2014.1.0 (current default)
