@zhangyongding ， 你有重现代码、步骤吗？
这个要想一下办法，因为机器在别的地方
是每次都报错，还是在特定情况下报错？
一定报错

- 可以在上面跑单元测试吗？如果能跑的话，可能是协程安全并发问题。
- 以前曾有哪个版本可以跑吗？
sm4的单元测试没有问题
但是sm9的单元测试有问题

sm9的问题，我会fix；如果能通过cipher/gcm_sm4_test.go的测试，应该没问题。
你的意思是说，上层代码调用的问题？
你可以使用go run -race 或者 go build -race 检测一下
使用race检测了一下我的程序，没看出有什么异常的地方，我这是一个命令行程序，理论上没有并发，一样的程序在别的机器上没有问题，就这个机器有问题
用CBC协议有问题吗？
- 这台机器的go是什么版本？
- 你用-race编译后运行，或直接go run -race运行，出问题后没有多一点信息？
SIGSEGV: segmentation violation指程序、代码访问非法内存地址，如果只在特定机器、环境有问题，况且cipher/gcm_sm4_test.go的测试也没有问题，这个不好定位问题。
go 版本是1.21.1
如果我在gcm_amd64.s Line 1686 插入一行XORQ ctx, ctx，运行测试可以获得如下错误：
panic: runtime error: invalid memory address or nil pointer dereference [recovered]

虽然不完全一样，不是SIGSEGV，但应该可以证明就是密文切片当时变成非法访问了。
gcm_amd64.s Line 1686 代码是：
PXOR (16*0)(ctx), B0我尝试写一个最简单的程序来触发这个情况，有没有可能是tlcp库有问题？因为是通过tlcp来调用gmsm的

看代码和跑https://github.com/Trisia/gotlcp/blob/main/example/client/mutual_auth_spec/ecdhe/main.go
https://github.com/Trisia/gotlcp/blob/main/example/server/mutual_auth_spec/main.go 没有问题，当然不是在目标机器。最好能写个重现代码。

作为tlcp的服务端时，0.21.4版本会报错，0.21.3正常，报错和前面的类似

v0.21.5-beta是可以的，cpu是E52620
前面的问题是不是有可能也是类似这个原因造成的？
