I'm confirming this bug on GNU Emacs 25.0.95.1
(x86_64-unknown-linux-gnu, GTK+ Version 3.14.5) of 2016-06-19
I'd like to issue a proper bug-report for it and I'd like to reference
David's mail in a reproducible way. Could somebody please tell me first
how to reference a specific message from some (GNU) emacs-devel mailing
list archive (preferably with Gnus)?

Actually it is documented in (info "(calc) Trigonometric and Hyperbolic
Functions")
Thanks you
