ORBit-2.0 cpp bug?

[Paco Moya <fmoya inf-cr uclm es>]

I get a segfault with this extremely simple example.
Any clue? The smart pointer associated to s.a seems
to be NULL...

tst.idl:--------------------------------------------
module test {
  typedef sequence<long> seq;
  struct sseq {
    seq a;
  };
};

main.cc:--------------------------------------------
#include "tst-cpp.h"
int main()
{
  test::sseq s;
  s.a->length(10);
}

Makefile:------------------------------------------
CFLAGS=`pkg-config --cflags ORBit-2.0`
CXXFLAGS=-g `pkg-config --cflags ORBit-2.0-cpp`
LDLIBS=-g `pkg-config --libs ORBit-2.0-cpp`
CC=g++
