Yes it does, bit Cppcheck is configurable and it is possible to suppress this
warning:
Quoted from Cppcheck's manpage:
--suppress=<spec>
Suppress a specific warning. The format of <spec> is: [error
id]:[filename]:[line]. The [filename] and [line] are optional. [error id] may
be * to suppress all warnings (for a specified file or files). [filename] may
contain the wildcard characters * or ?.
