Congrats with the footprint, some minor caveats though:
I googled for a datasheet and found one from Diodes, page 4 gives 1.39 mm by
1.40 mm for the "left" and "right" pads, so this "FreeRotateBuffer()"
Heisenbug should go away by itself.
Oh, and the marker is not in the Centre Of Gravity, so no easy
pick-and-place part from a 5000 units / tape & reel ;-)
@KMK: there are no "half bugs", bugs are boolean by nature, so either "0" or
"1" should do ;-)
Kind regards,
Bert Timmerman.
