程序退出时出现段错误 (-11)

Question

我正在尝试让 goocanvasmm 从 C++ 程序中运行。来自一对我组合代码片段并让程序绘制的地方。

但是，在程序终止时，会出现段错误。我不是普通 C++ 用户，因此，gdb 消息对我来说有些神秘。

这是代码。它创建一个 window，并在其中绘制一个 200x200 像素的黄色方块：

#include <gtkmm.h>
#include <goocanvasmm.h>
#include <iostream>
#define UI_FILE "gtk_foobar.ui"

int
main (int argc, char *argv[]) {
  Gtk::Main kit(argc, argv);

  //Load the Glade file and instiate its widgets:
  Glib::RefPtr<Gtk::Builder> builder;
  try {
    builder = Gtk::Builder::create_from_file(UI_FILE);
  }
  catch (const Glib::FileError & ex) {
    std::cerr << ex.what() << std::endl;
    return 1;
  }
  
  Gtk::Window *main_win = 0;
  builder->get_widget("main_window", main_win);
  
  Goocanvas::Canvas canvas;
  
  main_win->add(canvas);
  auto root = (canvas).get_root_item();
  auto rect = Goocanvas::Rect::create(100, 100, 200, 200);
  
  rect->property_stroke_color() = "yellow";
  rect->property_line_width() = 3;
  root->add_child(rect);
  
  main_win->show_all();

  if (main_win) {
    kit.run(*main_win);
  }
  return 0;
}

运行-时间错误信息（在程序终止时显示）：

Program has been terminated receiving signal 11 (Segmentation fault)

和 gdb 回溯：

#0  0x00007ffff5ae7d6c in free () at /lib64/libc.so.6
#1  0x00007ffff5a97736 in __cxa_finalize () at /lib64/libc.so.6
#2  0x00007ffff7d22946 in __do_global_dtors_aux () at /usr/lib64/libgoocanvasmm-2.0.so.6
#3  0x00007ffff7ffd060 in _rtld_local () at /lib64/ld-linux-x86-64.so.2
#4  0x0000000000000000 in  ()

如果我没记错的话，这似乎表明其中的析构函数有问题 libgoocanvasmm.

编辑： 我意识到（有点晚了），对于运行应用程序，还需要 UIFILE。这是 ("gtk_foobar.ui"):

<?xml version="1.0"?>
<interface>
  <!-- interface-naming-policy project-wide -->
  <!-- interface-requires gtk+ 3.0 -->
  <object class="GtkWindow" id="main_window">
    <property name="visible">True</property>
    <property name="title" translatable="yes">Hello World!</property>
    <property name="default_width">500</property>
    <property name="default_height">400</property>
    <child>
      <placeholder/>
    </child>
  </object>
</interface>

感谢@BobMorane 对程序进行了测试，发现库之间存在细微的版本差异。看来我的源码包和他的源码包都标为2.0.6，但内部有一个小区别，1.90.9和1.90.11，这很重要。

用1.90.11版本重新编译问题解决了！

查看更新日志没有发现令人震惊的差异，而是进行了一系列次要的兼容性更新。重新运行 valgrind确实显示此消息消失：
