[R] robustbase adjbox segfault - memory not mapped

[Baan]

Hi,

I encountered a segfault, memory not mapped error when  using adjbox in 
robustbase. In trying to recreate the issue I found that the error 
occurs only for large sample size. Here is the code.

 > require(robustbase)
Loading required package: robustbase
 > x <- rnorm(10)
 > y <- rep(1, 10)
 > adjbox(x ~ y) ## gives a plot
 > x <- rnorm(10000)
 > y <- rep(1, 10000)
 > adjbox(x ~ y) ## gives a plot
 > x <- rnorm(100000)
 > y <- rep(1, 100000)
 > adjbox(x ~ y)

  *** caught segfault ***
address 0xfffffffcc47af530, cause 'memory not mapped'

Traceback:
  1: .C(mc_C, x, n, eps = eps, iter = c.iter, medc = double(1))
  2: mcComp(x, doReflect, eps1 = eps1, eps2 = eps2, maxit = maxit,     
trace.lev = trace.lev)
  3: mc.default(x, ..., na.rm = TRUE)
  4: mc(x, ..., na.rm = TRUE)
  5: adjboxStats(unclass(groups[[i]]), coef = range, doReflect = doReflect)
  6: adjbox.default(split(mf[[response]], mf[-response]), ...)
  7: adjbox(split(mf[[response]], mf[-response]), ...)
  8: adjbox.formula(x ~ y)
  9: adjbox(x ~ y)
