Affected rules

• A27-0-4
• A18-1-1

Description

Alerts of both rules are triggered even if no C-style array or string is directly used. It may also be relevant that the usage of the # operator is covered by rule M16-3-2.

Example

#include <cassert>
#define ASSERT(expr) ((expr) ? static_cast<void>(0) : [] { assert(false && #expr); }())
class a_class
{
 public:
 void some_operator()
 {
 ASSERT(flag_);
 }
 private:
 bool flag_ = false;
};
int main()
{
 assert((false) && "A way to add an assert message");
 a_class instance;
 instance.some_operator();
}

A27-0-4 and A18-1-1 alerts are signaled on ASSERT(flag_); as well as assert((false) && "A way ... message");
