Additional info:
  how to fix:
   1. line 239:
	  char *ret;
	  struct servent *service;
       should be
     	  char *ret               = NULL;
	  struct servent *service = NULL;
       always good to init pointers to NULL.
   2. line 249
	ret = calloc((orig ? strlen(orig) : 0) + strlen(ret) + 2, sizeof(char));
      should be
	ret = calloc((orig ? strlen(orig) : 0) + strlen(tmp) + 2, sizeof(char));
      the core dump occurs at strlen(ret) as ret was not 
      initialized.
