当 运行 通过 callgrind 时，libhdfs 在常量池错误中抛出非法 UTF8 字符串
libhdfs throws Illegal UTF8 string in constant pool error when running through callgrind
我正在尝试 运行 通过 callgrind 完成我的流程。子进程之一（我需要跟踪）调用 libhdfs，当 运行ning 通过 callgrind 时抛出异常：

正常情况下运行我不会得到这个异常。知道发生了什么事吗？我是 valgrind/callgrind.
的新手
这似乎是 JVM 的一个问题，它在正常操作过程中生成大量 SIGSEGV，而 valgrind 不喜欢。我用以下参数克服了这个问题，调用 grind --vex-iropt-register-updates=allregs-at-mem-access.
