Description
I'm developing a sort of videoplayer in QML and C++. The software receives a stream of frames that will be converted in QPixmap.
To pass every QPixmap on QML GUI has been implemented a mechanism explained in this link: https://www.huber.xyz/?p=477
The software receives a frame every 5/10 ms and it works correctly also for a long period, but if I interact also with one of buttons that do nothing, I randomly get this SIGSEGV.
Following gdb backtrace:
Thread 1 "recorder-menu-q" received signal SIGSEGV, Segmentation fault.
