MISRA.CATCH.NOALL

Ellipsis exception handler is not the last one in a try-catch block.

MISRA-C++ Rule 15-3-7 (required): Where multiple handlers are provided in a single try-catch statement or function-try-block, any ellipsis (catch-all) handler shall occur last.

Rationale

If the catch-all handler is found before any other handler, that behaviour will be performed. Any handlers after the catch-all are unreachable code and can never be executed.

Example

void f1 ( )
{
   try
   {
      // ...
   }
   catch ( int32_t i ) // int handler
   {
      // Handle int exceptions
   }
   catch( ... )       // catch-all handler
   {
      // Handle all other exception types
   }
}
void f2 ( )
{
   try
   {
      // ...
   }
   catch( ... )         // catch-all handler
   {
      // Handle all exception types
   }
   catch ( int32_t i ) // Non-compliant — handler will never be called
   {
   }
}
