 9 Errors
 ********
 
      ^Z^Zquit
 
    This annotation occurs right before GDB responds to an interrupt.
 
      ^Z^Zerror
 
    This annotation occurs right before GDB responds to an error.
 
    Quit and error annotations indicate that any annotations which GDB
 was in the middle of may end abruptly.  For example, if a
 'value-history-begin' annotation is followed by a 'error', one cannot
 expect to receive the matching 'value-history-end'.  One cannot expect
 not to receive it either, however; an error annotation does not
 necessarily mean that GDB is immediately returning all the way to the
 top level.
 
    A quit or error annotation may be preceded by
 
      ^Z^Zerror-begin
 
    Any output between that and the quit or error annotation is the error
 message.
 
    Warning messages are not yet annotated.
