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:
I don't see it, but it looks to me like it may be a timing problem. I'm
guessing the destruction of the old window triggers events in the wrong
order and leaves rgl in an unstable state. Unfortunately, without being
able to reproduce this, it looks really hard to track down. Can anyone
reproduce it while running in gdb or some other debugger?

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
