Двойной вызов деструктора в qt

Доброго времени суток!

Не могу понять в чем проблема:

Program received signal SIGABRT, Aborted.

Не понятно почему деструктор ~FmAimControl() вызывается два раза.

Сам код:

if (table_->currentRow() == TAS_COMMANDER)
{
        fmAimControl_ = new FmAimControl(FmAimControl::COMMANDER, this);
        fmAimControl_->exec();
        fmAimControl_->deleteLater();
}

Внутри FmAimControl создается OesCommunication:

oesCommunication_ = new OesCommunication((formType == COMMANDER) ? commanderOesTask : aimerOesTask, this);

Помогите, пожалуйста, решить проблему.
