feval bug in 3.2.3

[Gunnar Rätsch]

Hi Octave team,

I'm using octave 3.2.3 on amd64 (compiled from source) and have  
problems with the feval function.
The code without feval works (1), while it does not work with eval (2):

1. fprintf('calling exp_galaxy(PAR_config)\n') ;
exp_galaxy(PAR_config) ;

2. Exp='exp_galaxy'
fprintf('calling feval(''%s'', PAR_config)\n', Exp) ;
PAR_exp = feval(Exp, PAR_config) ;

The function exp_galaxy is in the same source file as the code above  
(a local function).

feval works as expected in octave 3.0.4, but not in 3.2.3.
(I did not try versions between these versions as I could not get them  
compiled.)

Thanks a lot for your help!

All the best,

Gunnar

Hi again,

I tried it now with other octave versions. It works with 3.0.4 and  
3.0.5.
It does not work with 3.2.0, 3.2.2 and 3.2.3.

Hth, Gunnar

Since you haven't given a working code, I can't be sure, but probably
this is a duplicate of
