ignore-errors不是gdb的内置命令，可以使用下面的Python扩展为gdb添加该命令：

snippet.python

class IgnoreErrorsCommand (gdb.Command):
    """Execute a single command, ignoring all errors.
Only one-line commands are supported.
This is primarily useful in scripts."""
 
    def __init__ (self):
        super (IgnoreErrorsCommand, self).__init__ ("ignore-errors",
                                                    gdb.COMMAND_OBSCURE,
                                                    # FIXME...
                                                    gdb.COMPLETE_COMMAND)
 
    def invoke (self, arg, from_tty):
        try:
            gdb.execute (arg, from_tty)
        except:
            pass
