The report contains garbled Valgrind output from the CN21DeviceSdu build, including common_arch libraries and bin/deviceDemo. Start by reproducing the terminal corruption and reviewing the Valgrind output and encoding path; done means the terminal remains readable after extended use and the reported errors can be inspected normally.
