      1. Have a simple program running QJSEngine::evaluate (evaluate-cli.zip). 
        #include <QCoreApplication>
#include <QFile>
#include <QJSEngine>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    if (argc < 2)
        return -1;
    QFile inFile(argv[1]);
    inFile.open(QFile::ReadOnly);
    QJSEngine().evaluate(inFile.readAll());
    return 0;
}
      1. Build it on Qt 5.12.1.
      2. Run the program passing the attached input file as parameter: .5.toString(5)
        The program runs out of memory and crashes.
