Subject: [Rd] Rubbish values written with zero-length vectors (PR#14217)

Clearly the assignments v[[1]] <- v do not do anything useful, the problem is I
don't understand where the strange values left in v come from.

The same problem occurs with the 2.11.0 release r50716 and --vanilla. For
vanilla in Windows CMD mode I get different values in v, but ones which are to
me equally strange.

Many thanks for your help!

George Russell
