QCommandLineParser: suspend execution if built-in options were processed

Question

I am developing a Qt 5.x application whose main function is more or less like that (simplified):

int main(int argc, char *argv[])
{
   QApplication app(arg, argv);

   QCommandLineParser cmdLineParser;
   cmdLineParser.addHelpOption();
   cmdLineParser.addVersionOption();

   cmdLineParser.process(app);

   /// *** SOME INITIALIZATION STUFF *** ///

   app.exec();
}

I am experiencing some problems when I invoke the execution of application specifying the --version (or --help) option on command line: the application outputs the version (or the help) and then sometimes terminates with a segmentation fault...

I think it is due to the fact that when QCommandLineParser detects a built-in option on command line (--version or --help) simply calls QApplication's exit() for terminating the execution and this interferes with my own *** SOME INITIALIZATION STUFF *** (basically some other threads are started and maybe a prematurely call on exit() causes some problems)...

However, my question is: is it possible to make Qt avoid to go further in my *** SOME INITIALIZATION STUFF *** if a built-in option is detected on command line? In other words, is there a method to be called for knowing that a built-in option has been detected by the command line parser? Otherwise: is there a method for knowing that exit() has been called on application, and hence the application is terminating? If so, it would suffice to enclose my *** SOME INITIALIZATION STUFF *** in a if condition argumenting on that method and it would be fine...

Thanks for the support.

>> EDIT <<

I've done some further investigations... the behavior seems not be dependent on my own *** SOME INITIALIZATION STUFF ***... in fact even a "minimal, complete and verifiable example" as the following one sometimes terminates the execution with segmentation fault when the executable is triggered with --version on the command line:

#include <QApplication>
#include <QCommandLineParser>

int main(int argc, char *argv[])
{
    // Instantiate the application
    QApplication app(argc, argv);
    app.setApplicationVersion("1.0.0");

    // Prepare for parsing the command line
    QCommandLineParser cmdLineParser;
    cmdLineParser.setApplicationDescription("Test application");

    // Add support for command line standard options (help & version)
    cmdLineParser.addHelpOption();
    cmdLineParser.addVersionOption();

    // Perform actual parsing of command line
    cmdLineParser.process(app);

    // Let the application run
    return app.exec();
}

Just to clarify, I am using Qt 5.3.2 on an ARM device running Linux OS.
