Bug in 2020a using "ismember"?

When I am trying to use the "ismember" command in 2020a, I get werid stuffs. e.g.,

A = [1 2 3; 
    4 5 6; 
    7 8 9];
B = [4 5 6];
[Result,LocResult] = ismember(B,A,'rows')

is giving me

Result =
  logical
   0
LocResult =
     0

Am i doing something wrong here? I was expecting to get

Result =
       1
LocResult =
       2

I got what you expected to get. R2020a, on a Mac running the latest Catalina.

I would look and see if

which ismember

gives anything funky, and also try restarting MATLAB and see if you get the same result.

Next step is then probably a bug report.

restart works. wow. but why?

Magic. Probably had managed to alias the builtin somehow...

I had past problems where restart worked but nothing of this sort. must be magic! I am not sure how to accept comment as an answer though

'S OK...sometimes just the conversation is good enough... :)
