V596. Object was created but is not used. Check for missing 'throw' keyword.

Dec 23 2011

The analyzer has detected a strange use of the std::exception class or derived class. The analyzer generates this warning when an object of the std::exception / CException type is created but not being used.

For example:

if (name.empty())
  std::logic_error("Name mustn't be empty");

The error is this: the key word 'throw' is missing by accident. As a result, this code does not generate an exception in case of an error. This is the fixed code:

if (name.empty())
  throw std::logic_error("Name mustn't be empty");

This diagnostic is classified as:
