Comment (by 0kajuna0):

 Replying to [comment:3 Michael Koch]:
 > I don't see any bug here. Rectilinear output with large field of view
 does always look distorted.

 Distortion near the edges is expected. That's fine. It's the output width
 and height ratio that's wrong when not using the d_fov option, and thus
 the entire image is incorrectly distorted, not just the edges.
