octave and gsl

[Gorazd Brumen]

hi,

the reference to gsl was my next possibility. I compiled the following
script with mkoctfile

#include <octave/oct.h>
#include <math.h>
#include <gsl/gsl_sf_bessel.h>


DEFUN_DLD (gn, args,  , " gn function") {

  ColumnVector res (1);

  res(1) = gsl_sf_bessel_Jnu (2, 3);

  return octave_value ( res );

}


compile with mkoctfile gn.cc -lm -lgsl -lcblas
and it compiles ok. then when i run it in octave i get

*** glibc detected *** free(): invalid next size (fast): 0x08b8d140 ***
panic: Aborted -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Aborted


octave 2.1.72, ubuntulinux package.


can someone help me what i am doing wrong?

thank, g.
