I stumble on understanding difficulties for the currently supported
software functionality.

Three source code places are pointed out by the SmPL rule “to_do1”
as it would be expected.
Unfortunately, I miss the message “INFO: May the local variable "err" be
deleted?”
for the function “ptrace_hbp_set_addr” according to the SmPL rule “to_do2”.

Which adjustments will become relevant here?

Markus
