如何在沒有Valgrind錯誤的情況下調用JNI_CreateJavaVM？

在valgrind下編譯並運行下面的代碼時，我始終得到「無效的4號大小寫」錯誤。有沒有一種乾淨的方式調用JNI_CreateJavaVM（），以便valgrind不會拋出一個合適的？如何在沒有Valgrind錯誤的情況下調用JNI_CreateJavaVM？

#include <jni.h> 
#include <stdlib.h> 
#include <string.h> 

int main() 
{ 
    JavaVMInitArgs * vm_args = calloc(1, sizeof(JavaVMInitArgs)); 
    JavaVM * jvm = NULL; 
    JNIEnv * env = NULL; 

    vm_args->version = JNI_VERSION_1_6; 
    vm_args->nOptions = 0; 
    vm_args->options = NULL; 

    JNI_CreateJavaVM(&jvm, (void **)&env, vm_args); 

    return 0; 
}

這裏是我運行的valgrind命令：

valgrind --tool=memcheck --leak-check=yes --num-callers=20 --smc-check=all ./test

從我loooonng的valgrind日誌中的一個條目：

如果你設法做到這一點，你可以提供你的抑制文件嗎？ – Etherealone 2017-05-31 11:13:29

由於這是在JVM中你可以選擇壓制它。 Valgrind可以配置爲抑制特定的錯誤。你可以找到更多的細節here

上一個答案是正確的 - JVM執行valgrind不贊同的許多事情。您需要抑制這些錯誤，同時不要抑制您想要valgrind檢查的代碼中的錯誤。不幸的是，這是一個單調乏味的試錯過程。使用由valgrind生成的壓抑可以使這更容易，但它絕不是無痛苦的。如果最終發現「valgrind中堆棧跟蹤中的調用者太多」，請參閱此帖：http://stackoverflow.com/a/11040043/203044 – BillT 2012-06-14 19:33:15
