bytes.Buffer包的BUG

测试一段代码，发现Buffer包偶尔会Panic，记录一下： Test Panicked runtime error: slice bounds out of range /usr/local/Cellar/go/1.11.2/libexec/src/runtime/panic.go:513 Full Stack Trace /usr/local/Cellar/go/1.11.2/libexec/src/runtime/panic.go:513 +0x1b9 bytes.(*Buffer).readSlice(0xc000234030, 0x104d30a, 0x1ba1b80, 0xc0002b1312, 0x2, 0xc0002b0140, 0xc000001980) /usr/local/Cellar/go/1.11.2/libexec/src/bytes/buffer.go:418 +0x101 bytes.(*Buffer).ReadString(0xc000234030, 0xc00005c00a, 0xc00005c040, 0x1, 0x16513a0, 0xc00005c040) /usr/local/Cellar/go/1.11.2/libexec/src/bytes/buffer.go:437 +0x38 git-biz.360es.cn/connectors/utils/protocol/ssh.(*SSHClient).inputFlag(0xc000234000, 0x16566c0, 0x1bbb388) /Users/dongchaofeng/dongchaofeng/src/git-biz.360es.cn/connectors/utils/protocol/ssh/ssh.go:122 +0xec git-biz.360es.cn/connectors/utils/protocol/ssh.glob..func1.6() /Users/dongchaofeng/dongchaofeng/src/git-biz.360es.cn/connectors/utils/protocol/ssh/ssh_test.go:133 +0x302 git-biz.360es.cn/connectors/utils/vendor/github.com/onsi/ginkgo/internal/leafnodes.(*runner).runSync(0xc00009cd20, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, ...) /Users/dongchaofeng/dongchaofeng/src/git-biz.360es.cn/connectors/utils/protocol/ssh/ssh_test.go:16 +0xa2 testing.tRunner(0xc000206100, 0x15ea268) /usr/local/Cellar/go/1.11.2/libexec/src/testing/testing.go:827 +0xbf created by testing.(*T).Run /usr/local/Cellar/go/1.11.2/libexec/src/testing/testing.go:878 +0x353
