It's general (on all platforms), and the internal code for text.default
needs a safety check.

Dear Rexperts:
(R 2.0.1 on Windows XP Pro)
Is the following problem unique to my setup?
If it's a known problem, I didn't see it at
http://bugs.r-project.org/ nor find discussion in the archives.
plot(1:10)
loc <- c(5, 6)
text(loc, labels = "a")
Produces expected results according to ?xy.coords.
plot(1:10)
loc <- list(x = 5, y = 6)
text(loc, labels = "a")
No problem.
But:
plot(1:10)
loc <- list(5, 6)
text(loc, labels = "a")
crashes RGui.
("R for Windows GUI front-end has encountered a problem and ...")
R-FAQ:9.1 says:
If you call .C(), .Fortran(), .External() or .Call() (or
.Internal()) yourself (or in a function you wrote), you can
always crash R by using wrong argument types (modes). This
is not a bug.
I realize that I'm using the wrong argument type;
nevertheless, if the behaviour is general, it might be better
to generate an error.
For anyone with more know-how than I have, here are the details
of the crash:
AppName: rgui.exe AppVer: 2.1.41115.0 ModName: r.dll
ModVer: 2.1.41115.0 Offset: 000ef1b3
