The following program segfaults if any one of the integers:

canonical unicode k done

are not declared.

---------{ yaml_error.c begins }---------
#include <yaml.h>
#include <stdio.h>

/* Comment out 'canonical' to demonstrate segfault
  int canonical;
*/
  int unicode;
  int k;
  int done;

  yaml_parser_t parser;

  yaml_parser_initialize(&parser);
  yaml_parser_delete(&parser);
  return 0;
}
---------{ yaml_error.c ends }---------

Current trunk (revision 298) of libyaml does not compile no either my Ubuntu box or on OSX Tiger. There are 2 separate issues.

The first is a simple error in yaml_private.h. A Diff of this file is below.

The second problem I am not sure about. Build log is attached.
