Ok, so have Qt Creator and I tried creating just the most basic application, under Projects->Applications->Qt Gui Applications. The project was successfully created. Furthermore, when I compiled it, it appeared to work just fine.
11:07:38: Running steps for project Test1...
11:07:38: Configuration unchanged, skipping qmake step.
11:07:38: Starting: "C:\MinGW\bin\mingw32-make.exe"
C:/MinGW/bin/mingw32-make -f Makefile.Debug
mingw32-make[1]: Entering directory 'C:/Users/User/CProjects/Test1-build-Windows7Desktop-Debug'
mingw32-make[1]: Nothing to be done for 'first'.
mingw32-make[1]: Leaving directory 'C:/Users/User/CProjects/Test1-build-Windows7Desktop-Debug'
11:07:39: The process "C:\MinGW\bin\mingw32-make.exe" exited normally.
However, when I attempt to run it, I get this:
Starting C:\Users\User\CProjects\Test1-build-Windows7Desktop-Debug\debug\Test1.exe...
The program has unexpectedly finished.
C:\Users\Hunter\User\Test1-build-Windows7Desktop-Debug\debug\Test1.exe exited with code -1073741819
Every time. I start a new project, I do whatever, but I get that error. Now, I have also run in debug mode. I get this error:
The inferior stopped because it received a signal from the Operating System.
Signal name: SIGSEGV
Signal meaning: Segmentation fault
The offending file is qatomici386.h at line 132, and the specific function is QBasicAtomicInt::deref which states:
inline bool QBasicAtomicInt::deref()
{
unsigned char ret;
asm volatile("lock\n"
"decl %0\n"
"setne %1"
: "=m" (_q_value), "=qm" (ret)
: "m" (_q_value)
--> : "memory");
return ret != 0;
}
I have arrowed line 132.
I am running a 64 bit machine, but I believe I installed a 32 bit MinGW… but honestly I don’t even know if that is the real problem, let alone how to fix it if it is. I am very new to C++ and Qt.
As requested, here is my code:
mainwindow.cpp:
#include "mainwindow.h"
#include "ui_mainwindow.h"
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
}
MainWindow::~MainWindow()
{
delete ui;
}
main.cpp:
#include "mainwindow.h"
#include <QApplication>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();
return a.exec();
}
Test1.pro:

If anything else is needed, just ask.
Here is the complete debugging backtrace:

Update: I ran the example toy clock, and it worked fine. However, when I ran the calculator form, it resulted in the exact same error. I notice that the calculator form is in the normal project form: it has a .pro, and Header, Sources, and Forms folders. The toy clock on the other hand just has a .qmlproject file and a qml folder. It also fails at the same location with the same backtrace. I don’t actually know much about any of these things, but hopefully it will help find a solution.
I’ve been having the same problem, after just installing this whole environment.
I have been searching around, and there appears to be a bug on the Qt bug tracker at:
https://bugreports.qt.io/browse/QTCREATORBUG-7653
