shellcode不成功啊

[newBBnew]

根据你的说明使用也没有办法成功，下载你编译好的也没有成功：
error: could not compile nobody (bin "nobody") due to previous error; 14 warnings emitted

可能关键错误是这里：
note: #[deny(long_running_const_eval)] on by default
= note: this error originates in the macro $crate::__xref which comes from the expansion of the macro s (in Nightly builds, run with -Z macro-backtrace for more info)

根据说明是可以成功的，根据你的异常 只能看出 编译时长时间执行的常量表达式，有完整的日志信息吗？
