Details:

Octave for windows, 64bit, zip package installer. verified on 6.2.0 and 6.2.1
(build hg id: 50aa945836c3 Mon, Apr 26, 2021).  not set up to build so have
not verified on default branch.  

stumbled upon this in bug #60472, where pkg was reliably crashing to desktop.
turns out some odd behavior was calling rmdir("","s"). 

can reliably recreate crash by loading the GUI and running:


rmdir("")


assuming it's a crash and not just a forced close or exit because octave
doesn't retain any recent command history after the last normal session. 

note that this doesn't happen when run from the CLI.  in than case you just
get:


octave:2> rmdir("")
ans = 0
octave:3>
