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 -

I was running the program in the release build but linking against debug build libraries(Qtcored.lib). That was the issue.
