R devel - Nov 2006 - R freezes with text(...., srt = -1e-8) (PR#9347)

Version: 2.4.0
OS: Linux
Submission from: (NULL) (193.49.41.124)


Adding text to a plot makes R freeze if 'srt' is given a very small
negative
value, eg:

plot(1, type = "n")
text(1, 1, "some text....", srt = -1e-8)

But if 'srt = -1e-6' (or smaller) or 'srt = -1e-19' (or
greater), this works.

This seems to be OS-dependent: I observed this under Linux but not under Solaris
(I was not able to test under Windows or MacOS).

This looks like a duplicate of PR#9301, which was fixed a couple of 
weeks ago according to this NEWS entry:

     o   Drawing X11 rotated text was buggy for VERY small (negative)
         angle of rotation.  Reported by Ben Bolker.
