Details:

I have a function file 'f_test.m' with 2 functions defined:

function f_test()
  printf("f_test is executing..\n");
endfunction

function ret = f_2()
  printf("f_2 is executing..\n");
  ret = 7;
endfunction


The first function executes as expected.
Trying to execute the 2nd function 'f_2' issues an error as expected.
Then I use "autoload('f_2', 'f_test.m')" to load the 2nd function.
When I then call f_2 there is no more error as expected and all seems to be
ok, but the function does *Nothing*.
Only the second (and subsequent) call does execute the code in f_2.

Here is the sequence in the command window:

>> f_test
f_test is executing..
>> f_2
error: 'f_2' undefined near line 1 column 1
>> autoload('f_2', 'f_test.m')
warning: autoload: 'f_test.m' is not an absolute filename
>> f_2
>> f_2
f_2 is executing..
ans =  7
>>


In my opinion this is a bug - or am I doing something wrong?
To repeat this phenomena you have to close octave and restart it again, or use
"autoload('f_2', 'f_test.m', 'remove')" to unload f_2.
