While investigating bug #64783, I found another bug in the bytecode
interpreter, related to the number of output arguments.


>> __vm_enable__ (1)
>> f=@(x)[x{:}];
>> [a,b]=f({5,9})
a = 5
b = 9


Note that this should give an error (we are asking 2 outputs from f, but f
should return only 1 output vector). Disabling the bytecode interpreter
produces the correct result.


>> __vm_enable__ (0)
>> f=@(x)[x{:}];
>> [a,b]=f({5,9})
a =
   5   9

error: element number 2 undefined in return list
