source q , odd number or arguments segfaults ?

Hi , this almost works , but since I am mostly a copy and paste artist , I really dont get whats up here .... the below works , but only if the passed array is even in number .. e.g $dialog->set_authors( array('Pinky','And', 'The', 'Brain' ) ) ; works fine, but $dialog->set_authors( array('Pinky', 'And' ,'The', 'Brain', 'doh') ) ; segfaults ? whyfor ?? I am sure it is something to do with this... list = g_new( gchar *, len++ ) ; which I do not think is doing what I thought itwas doing since the other problem is that the array needs to have at least 4 elements or it segfaults ~ BUT if I call set_artists() with an array of 4 strings THEN call set_authors() with just 2 strings then its ok ... set_artists & set_authors are essentially the same code only with different names. e.g $dialog->set_authors( array('Pinky' ,'And' ) ) ; $dialog->set_artists( array('Pinky' ,'And' ,'The' , 'Brain' ) ) ; segfaults , but $dialog->set_artists( array('Pinky' ,'And' ,'The' , 'Brain' ) ) ; $dialog->set_authors( array('Pinky' ,'And' ) ) ; is fine /**************************************************/ static PHP_METHOD(GtkAboutDialog, set_authors) { int len, i=0; zval *php_list, **item; const gchar **list; NOT_STATIC_METHOD(); if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "a/", &php_list) == FAILURE ) { return; } len = zend_hash_num_elements(Z_ARRVAL_P(php_list)); list = g_new( gchar *, len++ ) ; zend_hash_internal_pointer_reset(Z_ARRVAL_P(php_list)); while (zend_hash_get_current_data(Z_ARRVAL_P(php_list), (void **)&item) == SUCCESS) { convert_to_string_ex( item ) ; list[i++] = Z_STRVAL_PP( item ) ; zend_hash_move_forward(Z_ARRVAL_P(php_list)) ; } gtk_about_dialog_set_authors( GTK_ABOUT_DIALOG(PHPG_GOBJECT(this_ptr)), list ) ; g_free(list); } /**************************************************/ Regards, Simon.
