    char * s        = StringValuePtr(self);
    unsigned i;

YAML
====

By default 1.8 uses Syck, 1.9 uses Psych. This ensures 1.9 uses Syck as well

YAML::ENGINE.yamler = 'syck' if defined? YAML::ENGINE and YAML::ENGINE.respond_to? :yamler

Change the stack size


Add:

// Fix stack size

#include <sys/time.h>
#include <sys/resource.h>
#define STACK_MULTIPLIER 512

void increase_stack_size(void)
{
    struct rlimit rlim;

    getrlimit(RLIMIT_STACK, &rlim);
    rlim.rlim_cur = RLIM_INFINITY;
    rlim.rlim_max = RLIM_INFINITY;
    setrlimit(RLIMIT_STACK, &rlim);
}

And:

VALUE rr_init(VALUE self){

  SEXP R_References;

  increase_stack_size(); // <- THIS IS THE NEW LINE
  init_R(0,NULL);
  // Initialize the list of protected objects
  R_References = R_NilValue;
  SET_SYMVALUE(install("R.References"), R_References);

  return self;

}
