[R] gremlin in rep()

[Richards, Tom]

NO, sorry, I am using NT 4.0.  I guess I was confused by someone else's
writing Splus 2000.
Under NT 4.0, R 1.1.0, the following crashes R:

> rep(1:3, c(4,2,-6))

but I still do get this:

> rep(1:3,c(4,5,-6))
[1] 1 1 1

and the following:

>  rep(1:3,c(2,5,-6))
[1] 1

My apologies to the list.
