First thing, can we check that the string_expand() call is working.. please
add a Debug() call:


        string_expand(newbuf, sizeof(newbuf), pat, buf, matches);
	Debug( LDAP_DEBUG_TRACE, "regex_matches: newbuf: %s\n", newbuf, 0, 0);
        if (( rc = regcomp(&re, newbuf, REG_EXTENDED|REG_ICASE))) {
                char error[512];
                regerror(rc, &re, error, sizeof(error));

                Debug( LDAP_DEBUG_TRACE,
                    "compile( \"%s\", \"%s\") failed %s\n",
                        pat, str, error );
                return( 0 );
        }
                                                            
Please run with:

	-d 1 -d 4 -d 32 -d 128

and send me the stderr output and your debug output..
