# addressing all remaining code scanning instances of warning C6011,
null pointer dereference
this pr aims to address more static code analyser warnings, specifically
null pointer dereferences. the majority of changes are solely to quieten
the analyser, as `malloc` and `calloc` are unlikely to fail, but this
should at least lead to the code analysis being more readable and
usable.
where functions addressed had existing failure strategies, they were
used, however some functions will now silently fail rather than
attempting to dereference a null pointer. if there is a preferred
solution in these cases, i will be happy to implement it.
