2.1.1 -- and 2.1.0 and 2.0.0 all showed the problem.

But thanks, Thomas, looking in "NEWS" of R-devel showed that
there was a fix for this in R-devel only --- too bad it didn't
make it for R 2.1.1.

And yes, the seg.fault doesn't happen in my version of R-devel.

Further note that only the very recent libc produces the
segfault for us.  Earlier versions, including the libc-2.3.2
used in our Debian sid (on AMD Opteron), do give the correct
error message instead of the seg.fault.
