 /**
  * Twig base exception.
  *
  * This exception class and its children must only be used when
  * an error occurs during the loading of a template, when a syntax error
  * is detected in a template, or when rendering a template. Other
  * errors must use regular PHP exception classes (like when the template
  * cache directory is not writable for instance).
  *
  * To help debugging template issues, this class tracks the original template
  * name and line where the error occurred.
  *
  * Whenever possible, you must set these information (original template name
  * and line number) yourself by passing them to the constructor. If some or all
  * these information are not available from where you throw the exception, then
  * this class will guess them automatically (when the line number is set to -1
  * and/or the filename is set to null). As this is a costly operation, this
  * can be disabled by passing false for both the filename and the line number
  * when creating a new instance of this class.
