Though am able to get application stack traces while running in debug mode
with Qt(debug) and massif, it aborts the application while launching app.
It does works fine when used with Qt 5.15 online commercial installer.

ASSERT failure in QCoreApplication::sendEvent: "Cannot send events to
objects owned by a different thread. Current thread 0x0x55a25cfacea0.
Receiver '' (of type 'QApplication') was created in thread
0x0x55a25cf32ef0", file kernel/qcoreapplication.cpp, line 553
Aborted (core dumped)

Can anyone let me know if there is any issue with the below configure line
which causes the assert error on ubuntu 20.04 with Qt 5.15.8?
