Sigill when debugging application with

  • I got the following error:

    Illegal instruction

    when I start in debug mode an application which create a QSslConfiguration variable.
    The application runs fine in both release and debug mode until I press "start debugging."

    It's a known behavior?

    This is the piece of code:

    QUrlQuery query;
    query.addQueryItem("fields", "value");
    QSslConfiguration conf;

    The debugger issues the above error on the declaration of 'conf'.

    That is an illegal instruction signal, which is pretty rare. Basically means the memory your program's residing in got corrupted somehow. So there's something very wrong. Check any callbacks, overwriting by mistake virtual tables and the such.
