Thank you, Rainer, for the report -- about the *development* version of R


Yupp.



Note that the segfault would not have happened in  'R 3.5.0 beta'
(today turning to be 'R 3.5.0 RC'  : RC := Release Candidate )
which we'd be very happy if you used extensively.


Ah, interesting news, that this does not occur with beta and RC.

It was a lapsus -- of mine -- not at all related to packageDate(),
corrected yesterday (svn r 74604).


Nice to here. Thanks for the fast response and greetings,
