`QObject: Cannot create children for a parent that is in a different thread.`

[rroohhh]

I am trying to run Jasper Gold (https://www.cadence.com/en_US/home/tools/system-design-and-verification/formal-and-static-verification.html).
Unfortunately it fails with a lot of repeated

(Parent is QProcess(0x12480b0), parent's thread is QThread(0x12480c0), current thread is QThread(0x2b6a240)
QSocketNotifier: Can only be used with threads started with QThread

Any hints on how to debug this further?
