 暂时或者条件删除/禁止停止点：

禁止断点4
(gdb) disable breakpoints 4
使能断点4
(gdb) enable breakpoints 4
(gdb) info break

3       breakpoint     keep y   0x00005555555547f9 in MyStrCopy2

	stop only if p=="string copy"
4       breakpoint     keep y   0x00005555555547ce in MyStrCopy2 
                                                   at strcopy.c:28
	stop only if s2=="string copy"
(gdb) disable breakpoints 4

	stop only if s2=="string copy"
用一次就停止断点4
(gdb) enable breakpoints once 4 
用一次就停止断点3-4
(gdb) enable breakpoints once 3-4
用一次就删除断点4
(gdb) enable breakpoints delete 4
用一次就删除断点3-4
(gdb) enable breakpoints delete 3-4
