Hello list,

I am just trying to solve the embedding issue (ruby-core:25927) and tried t=
o make a small testing program to narrow it down.
Actually I stumbled over another thing which I don't understand, why does t=
his program segtaults in the second run of the loop:

It's started like this: ./test test.rb

test.c
---------
#include <stdio.h>
#include <unistd.h>
#include <ruby.h>

RUBY_GLOBAL_SETUP

int
main(int argc,
  char *argv[])
{
  void *node =3D NULL;

  if(2 !=3D argc)
    {
      fprintf(stderr, "Usage: %s <FILE>\n", argv[0]);
      exit(1);
    }

  ruby_sysinit(&argc, &argv);
  RUBY_INIT_STACK;
  ruby_init();

  node =3D ruby_options(argc, argv);

  while(1)
    {
      ruby_run_node(node);

      sleep(1);
    }

  rb_exit(0);

  return(0);
}

test.rb
-------------
puts "foobar"
