使用SIGABRT的Java堆分析崩溃

我试图分析由C编写的方法分配的本机内存，并通过

JNI

插入到

JVM

。我安装了

$ valgrind --version
valgrind-3.13.0

并尝试使用以下选项运行JVM：

valgrind --tool=massif --massif-out-file=/tmp/massif-j.out java 
    -XX:+UnlockDiagnosticVMOptions //...

问题是它在创建核心转储时崩溃

谁能告诉我哪里会出错？这是因为

致命错误：反汇编失败，错误代码为：15#

？

Valgrind（以及基于Valgrind的工具）使用自修改代码。然而，HotSpot JVM严重依赖于动态代码生成，包括覆盖和修补先前生成的指令。即使禁用了JIT编译器，这一点仍然有效，因为HotSpot还为解释器和运行时存根使用动态代码生成

对于本机内存分配评测，您还可以使用或。后者具有与Java运行时集成的优点，即它可以显示本机和Java框架的混合堆栈跟踪。此外，这两种工具都有相当小的性能开销，不像Valgrind虚拟化正在运行的程序

我还尝试编译库并将其链接到

-fsanize=address

，但不幸的是，它无法捕获简单的

malloc（sizeof（char））从
JNI
方法调用。在JVM下运行时使用地址消毒器是否有问题？@St.Antario否，JVM不应影响
-fsanize=address
