Synopsis

Throw of exceptions by pointer

Enabled by default

Yes

Severity/Certainty

Medium/Medium

Full description

An exception object of pointer type is thrown and that pointer refers to a dynamically created object. It might thus be unclear which function is responsible for destroying it, and when. This ambiguity does not exist if the object is caught by value or reference. This check is identical to MISRAC++2008-15-0-2, MISRAC++2023-18.1.1.

Coding standards

Code examples

The following code example fails the check and will give a warning:

class Except {};

Except *new_except();

void example(void)
{
    throw new Except();
}

The following code example passes the check and will not give a warning about this issue:

class Except {};

void example(void)
{ 
    throw Except();
}
