Da Vinci sprint 10, Da Vinci sprint 11
I build the quicknanobrowser from the examples in the qtwebengine repository.
When browser to a content heavy site (e.g. reddit) and scrolling rapidly or pressing pagedown I get a SIGBUS
To control the browser I used the vnc platform.
gdb backtrace (edited with debug info):
