Thanks. Unfortunately I still get the same problem as shown above.
poly1 = [

[125, 0, 0],
[125, 235, 0],
[125, 235, 0],
[136.375, 284, 0],
[171, 312, 0],
[-1, 312, 0]
];
poly2 = [
[-1, 0, 30],
[145.624, 0, 30],
[145.624, 235, 30],
[145.624, 235, 30],
[156.999, 284, 30],

Thanks. Unfortunately I still get the same problem as shown above.
Just to clarify: Is your problem that the tessellation of the concave endcaps is not correct? ..or are your experiencing other issues?
The endcap issue is a bug and will be fixed. I’ll open an issue.

I don't know what an endcap is, but those things highlighted in pink in the
concave region shouldn't be there at all. That's my problem.
By adding a cube(1); after the skin call() the problem is corrected,
however, the shape now lacks the two large faces:
skin([poly1, poly2]);
cube(1);

That’s odd…
Could you verify that you have the latest development snapshot of OpenSCAD and the latest master of both scad-utils and list-comprehension-demos?
If it still doesn’t work, you’re experiencing a system-dependent issue which would be high priority to fix.

Today I can't reproduce the problem above. Instead it's back to the original
problem.
http://forum.openscad.org/file/n11367/openscad_error.png
I redownloaded skin.scad. I believe I have the latest version of scad-utils
because I downloaded it yesterday (clicked download zip on github). Also I
downloaded the latest dev snapshot of x64 openscad for windows. No
difference.

Sorry, forgot to add the cube() call. It works correctly in the latest
openscad snapshot. :) Great work.

Sounds like you want some sort of variation of this:
This takes a set of points in ccw order (from above) and then appends
another set of points in ccw order (from above) and creates a skin from
that. If the direction is -ve in the z-axis, the side wall faces will be
flipped.
Sorry, this is not production code and was actually a test for something
else, but I think you can get the idea.
