This is most relevant to R-sig-mac. There are two different rgl devices
on OS X, depending how you are running this. One based on X11 and one
on Apple's GL. In particular, are you using command-line R or R.app?
I seem to be able to reproduce it using R.app, in which case it is most
definitely for R-sig-mac, and a workaround is to use command-line R.

This is really odd, and probably 100% local to me, but I'm at a loss as to a
next step.
After narrowing things down, here's how to reproduce:
library("rgl")
showSomething <- function() {
open3d()
points3d(rnorm(10),rnorm(10),rnorm(10))
axes3d()
title3d('main','sub','xlab','ylab','zlab')
}
showSomething() # works as expected.
# Close the current rgl window
showSomething() # crashes R with the following report:
*** caught segfault ***
address 0x0, cause 'unknown'
Traceback:
1: .C(rgl_dev_open, success = FALSE)
2: rgl.open()
3: open3d()
4: showSomething()
This will probably work fine for any of you, it's so simple and fundamental.
If I don't close the open rgl windows, it doesn't crash, and I can execute the
function over and over successfully. And the same thing happens if I just do
the commands inside the function individually. SessionInfo() below.
Perhaps something is corrupt with my X11 window system? Thanks, Bryan
