gtk 段错

vivian2086

这段代码啥问题。只能打印here 1 就seg fault 了。段错在gtk_dialog_run.

新建一个测试工程测试这几行代码是没问题的。有没可能是堆用完了？这种问题怎么调试

{
          printf("here 1\n";
          GtkWidget *w = gtk_file_chooser_dialog_new( "aa", NULL,
                                                      GTK_FILE_CHOOSER_ACTION_OPEN,
                                                      GTK_STOCK_OK, GTK_RESPONSE_OK,
                                                      GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL,
                                                      NULL);
          if ( gtk_dialog_run( GTK_DIALOG( w ) ) == GTK_RESPONSE_OK ){
               printf("here 2\n";
          }
          printf("here 3\n";
          return;
}
