In TeX.SX Label position angle problem question is shown that not all angles are valid as anchors for labels.
A code like:
\documentclass[tikz]{standalone} \usetikzlibrary{quotes} \begin{document} \begin{tikzpicture}[label distance=1cm] \foreach \x in {0,10,...,360} { \coordinate["\x:$F$"] (F) at (0,0) {}; \draw[red] (0,0)--++(\x:2cm);} \end{tikzpicture} \end{document}
should draw label "F" on angles 0, 10, 20, ... but it produces the result in attached file.
It's not a bug.
Try this example:
Then read the pgfmanual p.241 (v3.0).
Closing based on Paul's comment.
I'm sorry but I don't understand how Paul's comment works and how information in page 241 explains it. Its result is just

while I expected 36 labels arround a central node. If you look at http://tex.stackexchange.com/questions/163762/label-position-angle-problem you can find an answer from Mark Wibrow which also suggestes at least a precission problem computing labels positions.
Page 241: the automatically choosen anchors for labels are always
north
,north east
,east
, etc. or 0°, 45°, 90°, 135°, etc (multiples of 45°). They never are 35° or 73°...Last edit: Paul Gaborit 2015-08-03
Thanks for your fast reaction. I conclude that I was somewhat too fast. I reopened the ticket for investigation.
Christian,
Paul's code works as expected. It was my fault. The figure I attached before was produced with a "spurios" code in my test file. Paul's code produces 36 labels which are anchored on its "nearest to center corner" and not on its center. I understand this is the reason for the wrong aligned for
draw=none
labels.Should have been closed again. Not a bug.
