[R] code to provoke a crash running rterm.exe on windows

[Anthony Damico]

hi, here's a minimal reproducible example that crashes my R 3.3.0 console
on a powerful windows server.  below the example, i've put the error (not
crash) that occurs on R 3.2.3.

should this be reported to http://bugs.r-project.org/ or am i doing
something silly?  thanx
