Am unable to locate core dump even after setting ulimit -c unlimited. Not
sure if there is any system configuration in ubuntu 20.04 or application
which doesnot allows to generate coredump file.
Shall try to run on another ubuntu 20.04 if it makes any difference.
However, when I run the application with gdb, below are the traces:
ASSERT failure in QCoreApplication::sendEvent: "Cannot send events to
objects owned by a different thread. Current thread 0x0x555555f73320.
Receiver '' (of type 'QApplication') was created in thread
0x0x555555ed0f20", file kernel/qcoreapplication.cpp, line 553
Thread 4 "Thread (pooled)" received signal SIGABRT, Aborted.
