Custom Assertion Failure Behaviour

First of all, there is a need to define a custom assertion failure report class which inherits from comms::Assert and overrides pure virtual member function fail():

#include "comms/comms.h"
class MyAssert : public comms::Assert
{
public:
    MyAssert(...) {...} // The constructor may receive any parameters needed
protected:
    virtual void fail(
        const char* expr,
        const char* file,
        unsigned int line,
        const char* function) override
    {
        ... // Do the failure report
    }
private:
    ... // Any data members
}

The second stage is to enable/register the the custom assertion failure behaviour:

int main(int argc, const char* argv[])
{
    comms::EnableAssert<MyAssert> enabledAssert;
    // From this point custom assertion failure bahaviour takes place.   
    ...
}

It is also possible to override custom assertion failure behavior several times:

int main(int argc, const char* argv[])
{
    comms::EnableAssert<MyAssert> assert1;
    // From this point custom assertion failure bahaviour takes place.   
    ...
    { 
         comms::EnableAssert<SomeOtherMyAssert> assert2;
        // From this point different custom assertion failure bahaviour 
        // defined in SomeOtherMyAssert class takes place.    
        ...
    } // assert2 is out of scope, the custom assertion failure behavior
      // registered with assert1 is restored.
    ...
}
