Debugging with GDB
^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.
