[Help-gsl] Segmentation fault with gsl_vector_alloc

[notinh notien]

In regard with the previous email about gsl_vector_alloc's segmentation 
fault.  I am currently using gsl-1.6, g++ (gcc) 3.3.3-7 (Redhat FC 2)

So I decided to step into gsl to see if the error is mine or ....

Breakpoint 1, setupFitting () at main.cpp:574
574           gsl_vector *x = gsl_vector_alloc(6);
(gdb) s
gsl_vector_alloc (n=6) at init_source.c:26
26        if (n == 0)
Current language:  auto; currently c
(gdb) print n
$1 = 6
(gdb) s
32        v = (TYPE (gsl_vector) *) malloc (sizeof (TYPE (gsl_vector)));
(gdb) print v
$2 = (gsl_vector *) 0x9f31388
(gdb) s

Btw, I found it is a bit weird to have such a long run stacks like this 
because I was trying to run through this loop 4 times.  However, right at 
the first run (I know the first run because I printed out some results only 
once) I got this seg fault.

Thanks once again for all your help.
