我已经包含了源代码、错误和堆栈跟踪。我该如何解决这个问题？我需要有关如何继续处理此

源代码的指针（解释）：

QFile xmlInputFile(".\\gatewayipmonitor.xml");  
xmlInputFile.open(QIODevice::ReadOnly);

QByteArray xmlData(xmlInputFile.readAll());

QDomDocument doc;
doc.setContent(xmlData);

QDomElement docEl(doc.documentElement());
const QString tagName(docEl.tagName());

docEl.text();

执行最后一行时 - 我收到消息

Windows 在tests.exe 中触发了断点。
这可能是由于堆损坏造成的，这表明存在错误 test.exe 或它加载的任何 DLL。
这也可能是由于用户在tests.exe执行时按了F12 重点。
输出窗口可能有更多诊断信息。 ”

当我点击继续时 - 我进一步收到消息 -

程序：...n\tests\Release\tests.exe 文件： f:\dd\vctools\crt_bld\self_x86\crt\dbgheap.c
表达式：_CrtIdValidHeapPointer(pUserData)

堆栈跟踪：

原文

I have included the source, the error and the stack trace. How do I resolve this issue? I need pointers(explanation) on how to proceed regarding this

Source Code :

QFile xmlInputFile(".\\gatewayipmonitor.xml");  
xmlInputFile.open(QIODevice::ReadOnly);

QByteArray xmlData(xmlInputFile.readAll());

QDomDocument doc;
doc.setContent(xmlData);

QDomElement docEl(doc.documentElement());
const QString tagName(docEl.tagName());

docEl.text();

When the last line is executed - I get the message

Windows has triggered a breakpoint in tests.exe.
This may be due to a corruption of the heap, which indicates a bug in
tests.exe or any of the DLLs it has loaded.
This may also be due to the user pressing F12 while tests.exe has
focus.
The output window may have more diagnostic information.
"

When I click continue - I further get the message -

Program: ...n\tests\Release\tests.exe File:
f:\dd\vctools\crt_bld\self_x86\crt\dbgheap.c
Expression:_CrtIdValidHeapPointer(pUserData)
