c++ - Qt 堆内存损坏

Question

我正在编写一个 Qt 4.6 应用程序(没有 qt 设计器)，当我关闭该程序时，我从 Visual Studio 收到此错误:

Windows has triggered a breakpoint in Test.exe.

This may be due to a corruption of the heap, which indicates a bug in Test.exe or any of the DLLs it has loaded.

This may also be due to the user pressing F12 while Test.exe has focus.

The output window may have more diagnostic information.

这是源代码:

• TesterWindow.h http://pastebin.com/SEVr8x40
• TesterWindow.cpp http://pastebin.com/MYUtZZGw
• Device.h http://pastebin.com/bXKxVrmW
• Device.cpp http://pastebin.com/H1kMcRes
• ExtWiiMote.h http://pastebin.com/uX3HT9Yw
• ExtWiiMote.cpp http://pastebin.com/p2TKZdHv

(你编译不了，我没法分享用过的库)

怎么了？

Answer 1

在 ExtWiiMote.h 中你声明了

QLabel* dots[3][3];

并在 ExtWiiMote.cpp 中使用 dots[3][0]...。

修复 dots 数组大小，也许你会没事的。
