Example code:

struct A {}

void foo(bool cond){}

void main()
{
    A a;
    int i;

    assert(a);      // type A does not have a boolean value
    assert(i || a); // type A does not have a boolean value
    assert(0 || a); // OK

    if(a) {}        // type A does not have a boolean value
    if(i || a) {}   // type A does not have a boolean value
    if(0 || a) {}   // type A does not have a boolean value

    foo(a);         // cannot implicitly convert type A to bool
    foo(i || a);    // OK
    foo(0 || a);    // OK
}


The three examples that pass really should be errors.

Regards
