Many thanks.

Is this enough or must I really provide an example?

Not sure. Does this help? "It's not a new/delete - the ClassName code uses smart pointers I suspected we were passing around a std::shared_ptr<namespace::classname> </namespace::classname> Which actually pointed to a derived builder and the lack of virtual destructor on ClassName meant the derived destructor wasn't called when the shared pointer went out of scope"

Hi, Is it possible that a memory leak was occurring because of a missing virtual destructor? virtual ~ClassName() {} If the default behaviour of the virtual destructor prevents the leak, why didn't cppcheck warn about it? Thanks.

You can close this. The libfec.a I was using was a Linux library, sorry. Also from...
