calling feval from standalone c++ code

I'm trying to call feval from a standalone
c++ code linked to the octave libraries.

The code given here will compile but segfaults
on execution. (I've tried all sorts of LD_LIBRARY_PATHs)

Could someone tell me if calling
feval this way makes any sense at all?

If anyone wonders why I'm doing this:
I'm trying to write an Inline::Octave perl
module.  Right now I can access all of
liboctave from Inline::CPP with the right
compile options. If there were a way
to access compiled octave functions and
*.m files, this would be really powerful.

here is the code   ------------
#include <octave/oct.h>
#include <octave/parse.h>
  octave_value_list i;
  i(0)= 1.0;
  i(1)= 1.0;
  octave_value_list o= feval("rand",i,1);
  return (int) ( o(0).double_value() );
----------compile with -------------

cc -I/usr/local/include/octave \
   -L/usr/local/lib/octave -loctave -loctinterp -lcruft \
   -ldl -lstdc++ -lg2c -lncurses \
   -L/usr/src/octave-2.1.34/kpathsea  -lkpathsea \
   -L/usr/src/octave-2.1.34/readline  -lreadline
