Thank you, Bjørn-Helge.
A shorter version is

   plot(1:500, col = gl(2,250))

Interestingly, with much shorter vectors of length (n), the correct warning is produced (n times).
And once that has happened, you can use longer vectors without any problem.

As you said ``issued just after starting R'' seems quite relevant.

When run in 'R -d gdb', the backtrace ("bt") seems to indicate that the problem is happening during the (C-level) warning() call.
