R process killed when allocating too large matrix (Mac OS X)

Hi Simon,

... all interesting (but quite a bit above my head). I only read
'Linux' and want to throw in that this problem does not appear on
Linux (it seems). I talked about this with Martin Maechler and he
reported that the same example (on one of his machines; with NA_real_
instead of '0's in the matrix) gave:

  Error: cannot allocate vector of size 70.8 Gb
    Timing stopped at: 144.79 41.619 202.019

... but no killer around...

Cheers,
Marius
