I can reproduce:
eigen(crossprod(matrix(1:2000, 50)) + (0+0i), T, T)

Traceback:

  1. .Call("La_rs_cmplx", x, only.values, PACKAGE = "base")
  2. eigen(crossprod(matrix(1:2000, 50)) + (0 + (0+0i)), T, T) ##---- after restart > sessionInfo() R version 2.13.1 (2011-07-08) Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)

locale:
[1] en_US.UTF-8/en_US.UTF-8/C/C/en_US.UTF-8/en_US.UTF-8

attached base packages:
[1] stats graphics grDevices utils datasets methods base

With OSX 10.5.8

Also happens with 32 bit R
[R.app GUI 1.41 (5874) i386-apple-darwin9.8.0]
