R devel - Jul 2002 - plotting density(rnorm(1000)) crashed once (PR#1837)

How can a random result be reproducible?  You could have told us the seed
in use!   I've tried this ten times without a crash, on two separate
machines, one XP and one 2000.

There is advice on how to do this in a usable way in the rw-FAQ.

R is already well-protected against that HP bug (which does not occur on
WIndows 2000 BTW, and was discovered by me under Win98), and I do have an
HP printer installed.
