Hello there, [linux-4.5-rc3/arch/arc/kernel/unwind.c:629]: (warning) Invalid test for overflow 'ptr+len<ptr'. Condition is always false unless there is overflow, and overflow is Undefined Behaviour. Source code is ??????? if (ptr + len < ptr || ptr + len> end) ??????????? return -1; Suggest code rework. Regards David Binderman
