Details:

Hi, here's a minimum working example, in 3.8.2, to turn on broadcasting
globally, without asking it to:


## Run the following two commands
warning ("error", "Octave:broadcast");

## Now, execute this function with an error:
testbadbroadcastmy(1);

## Now, broadcasting is on, globally!
cc=[1 1]+randn(2,2);

## As you see above, broadcasting has been turned on globally, even though it
shouldn't have!

## where, define this function in a file:


function out=testbadbroadcastmy(aa,bb)
  _bad2();
  warning ("off", "Octave:broadcast","local"); ## Notice that it ONLY does
this locally. 
  out=bb;
endfunction


function _bad2 ()
  tmp=1;
endfunction;
