Environment: linux x64, compiler gcc 4.x

Project has following structure:

static library "slib"
-- inside this library, there is static object "sobj"

dynamic library "dlib"
-- links statically "slib"

executable "exe":
-- links "slib" statically
-- links "dlib" dynamically

at end of the program, "sobj" is destructed twice. That behaviour is expected, BUT it is destructed twice at same memory address, i.e. same "this" in destructor - as the result there is double destruction problem. I think it is due some symbol overlapping.

What the solution for that conflict? Maybe some linking option?


Here is test case:


main_exe.cpp

#include <cstdlib>

#include "static_lib.h"
#include "dynamic_lib.h"

int main(int argc, char *argv[])
{
    stat_useStatic();
    din_useStatic();
    return EXIT_SUCCESS;
}

static_lib.h

#ifndef STATIC_LIB_H
#define STATIC_LIB_H

#include <cstdio>

void stat_useStatic();
struct CTest
{
    CTest(): status(isAlive)
    {
        printf("CTest() this=%d\n",this);
    }
    ~CTest()
    {
        printf("~CTest() this=%d, %s\n",this,status==isAlive?"is Alive":"is Dead");
        status=isDead;
    }
    void use()
    {
        printf("use\n");
    }
    static const int isAlive=12385423;
    static const int isDead=6543421;
    int status;

    static CTest test;
};

#endif

static_lib.cpp

#include "static_lib.h"

CTest CTest::test;

void stat_useStatic()
{
    CTest::test.use();
}

dynamic_lib.h

#ifndef DYNAMIC_LIB_H
#define DYNAMIC_LIB_H

#include "static_lib.h"

#ifdef WIN32
#define DLLExport __declspec(dllexport)
#else
#define DLLExport 
#endif
DLLExport void din_useStatic();


#endif

dynamic_lib.cpp

#include "dynamic_lib.h"

DLLExport void din_useStatic()
{
    CTest::test.use();
}
