packageDate() segfaults, if used without argument

Out of curiosity, I played a bit with the new function packageDate()
from April, 4th. All works fine, except using it without any argument.
In this case, it segfaults:


#> packageDate()
Error in packageDescription(pkg, lib.loc = lib.loc, fields = date.fields) :
  argument "pkg" is missing, with no default

 *** caught segfault ***
address 0x77bc3c0, cause 'memory not mapped'
Segmentation fault (core dumped)


My system is FreeBSD 12.0-CURRENT amd64 with R-devel (r74601).

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

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.

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

Ah, interesting news, that this does not occur with beta and RC.
Nice to here. Thanks for the fast response and greetings,
