Hello,
I’m testing an in house Qt application at sequality software engineering. The application works fine on every module i tested so far and on Raspberry Pi 3 & 4. A problem occurred after updating the Colibri i.MX6DL to boot2Qt 5.14.0. The Module is throwing the SIGSEGV signal, some time after starting routing in MapboxGL.
This is the stacktrace at the time the signal occures:
