I'm not sure what causes this, but I just discovered some odd perimeters generated from a drill bit sharpening jig I was making.

I verified the generated G-code in gcode.ws, so it's not an issue with the preview.

I do not know what is causing the trouble, but if you rotate item (45deg), problem seems to disappear.

I see it too. I tried slicing with 1.2.5 and the perimeters are fine, so something between 1.2.5 and 1.2.6.

Any idea if this problem is in 1.2 5 or 1.2.4?

Thank you. That looks like an issue in the Clipper library. I isolated the test case and escalated the report to the kind Clipper author:
