      All of the QByteArray .toInt() .toLong(), etc methods call the internal function nulTerminated() which ensures that the buffer being processed is terminated with a NUL character.

      .toDouble() doesn't do this – which would not be a problem except for the fact that the numLen argument being passed to qt_asciiToDouble is not being respected inside that function (it may read past the end of buffer).  See related issue: QTBUG-85580.

      As such, I suggest either fixing QTBUG-85580 above or if not, then making .toDouble() operate on an enforced nulTerminated() buffer.
