When I draw a simple curve with the pen tool, even if I have made each previous point a "corner" point, I get this result.

example illustrator path vs stroke

The red curve is the actual pen tool path and the black is the stroke. This is bizarre and I've never run into this issue before.

I eventually determined the problem: I had started with a box, used Style -> Round Corners to add round corners to it, and then started slicing and dicing one side to achieve the shape I wanted without using Object->Expand Appearance first. Once I used Expand Appearance, I was able to make changes to the path without the unexpected behavior.
