QSerialPort seems to be broken in Qt 6.4.2
-
Since I've updated to Qt 6.4.2 I have very frequent software crashes (Segmentation faults) when using serial ports. Mainly the function waitforbyteswritten seems to cause it. Switching back to Qt 6.2.4 solved the problem completely. In addition of crashes I've noticed that sometimes obviously rubbish data was sent out which caused the hardware data acquisition devices to send back suspicious data.

@hkottmann Can you post the stack trace after such a crash?
You can also check https://bugreports.qt.io/secure/Dashboard.jspa to see whether this was already reported. -
