going beyond the length of a vector - seg fault if length is 0 but not otherwise

[paciorek]

Trying to write into a vector beyond its length is protected against - it seems that the write simply doesn't happen.

However, if the length of the vector is 0, then there is a segfault. We might see if we can protect against this.

myfun <- nFunction(
    fun = function() {
        y = numeric(length=0)
        y[3] = 7
        return(y)
    }, returnType = 'numericVector')
