Problem with gsl_multifit_fdfsolver_alloc().

[Tiago de Paula Peixoto <count0 at fissionauthority dot com>]

Hello.

 The manual says that the function gsl_multifit_fdfsolver_alloc() should
return a null pointer if there's no memory available and invoke the error
handler. But apparently, the function does _not_ return a null pointer,
and only invokes the error handler.

I'm sending attached the example in the manual slightly modified to show
this problem. Right after it tries to allocate memory for the solver I put
the condition:

if (s == NULL)
  exit(1);

But if I put a large value for N (18000 is enough in my machine) the error
handler is called but the program doesn't exit and segfaults later. Using
GDB I saw that the value for 's' wasn't null after the function failed to
allocate memory.

Is there something I'm missing or is this a bug?
