This will likely generate a lot of Fake positives in certain code bases; if so, flag only switches that manage most but not all instances
110: Will not compose your own double-checked locking for initialization and CP.100: Don’t use lock-totally free programming Unless of course you Unquestionably really need to, then do it in a traditional sample.
Also, most true-world jobs contains code from quite a few resources, so standardizing on one design and style for all code is commonly not possible.
Flag declaration of the C array within a function or class that also declares an STL container (in order to avoid abnormal noisy warnings on legacy non-STL code). To fix: A minimum of alter the C array to some std::array.
An mistake ensures that the perform can't attain its advertised reason (including setting up postconditions).
In any other case, it should be guarded to ensure only derived courses can invoke it in their own personal destructors, and nonvirtual because it doesn’t need to behave pretty much virtual.

The habits of arrays is undefined from the presence of destructors go now that toss simply because there isn't any sensible rollback behavior that can ever be devised. Just Consider: What code can the compiler deliver for constructing an arr the place, Should the fourth object’s constructor throws, the code has to surrender As well as in its cleanup mode tries to connect with the destructors of the by now-built objects … and one or more of All those destructors throws? There is no satisfactory solution.
