问有没有人能够在使用共享DLL的Windows 64位应用程序上集成tcmalloc？

EN

string Parameters::GetExecutablePath()

    string  execPathStr;
    char exeFilePath[ MAX_PATH +1];
    if ( GetModuleFileName( NULL, exeFilePath, MAX_PATH ) )
    {
        //The line of code below is where the app crashes.
        //It calls operator new in crt/src/new.cpp. I verified the call to malloc
        //is forwarded to tcmalloc. 
        *execPathStr = string(exeFilePath);* //creates and deletes a temporary and then crashes

        long dir_pos = execPathStr.rfind( FT_DIR_SLASH ) ;
        execPathStr = execPathStr.substr( 0, dir_pos+1 );
    }

    return execPathStr;

}

~_String_val()
{   
    // destroy the object
    typename _Alloc::template rebind<_Container_proxy>::other _Alproxy(_Alval);
    this->_Orphan_all();
    _Dest_val(_Alproxy, this->_Myproxy);
    **_Alproxy.deallocate(this->_Myproxy, 1);**
    this->_Myproxy = 0;
}


void deallocate(pointer _Ptr, size_type)
{   
    // deallocate object at _Ptr, ignore size
    **::operator delete(_Ptr);**
}

This is where it crashes. the pHead->nBlockUse is 0. 
crt/dbgdel.cpp:

void operator delete(
        void *pUserData
        )
{
    //code omitted for brevity
    /* verify block type */
    **_ASSERTE(_BLOCK_TYPE_IS_VALID(pHead->nBlockUse));** //crashes here
}

void __cdecl operator delete(void* p)
{
#if !defined(_AFX_NO_DEBUG_CRT) && defined(_DEBUG)
        **_free_dbg(p, _NORMAL_BLOCK);** <-------- this function gets called 
#else
        free(p);
#endif
}

extern "C" _CRTIMP void __cdecl _free_dbg(
        void * pUserData,
        int nBlockUse
        )
{
 _mlock(_HEAP_LOCK);

        __try {
            /* allocate the block
             */
            **_free_dbg_nolock(pUserData, nBlockUse);**
        }
   __finally {
            /* unlock the heap
             */
            _munlock(_HEAP_LOCK);
        }
}



extern "C" void __cdecl _free_dbg_nolock(
        void * pUserData,
        int nBlockUse
        )
{
    //code omitted for brevity

    /*
    * If this ASSERT fails, a bad pointer has been passed in. It may be
    * totally bogus, or it may have been allocated from another heap.
    * The pointer MUST come from the 'local' heap.
    */
    **_ASSERTE(_CrtIsValidHeapPointer(pUserData));** <-------- crashes here
