VC++ MFC Detected memory leaks

Expected behavior

I used VS2015 to create a new MFC multi-document project, and then introduced the db library into the project, only the private declaration in the class:

include <rocksdb/db.h>

CString strFilePath = GetCurPrjDir() + _T("\ConfigData\testdb"); std::string dbpath = CT2A(strFilePath.GetBuffer()); rocksdb::DB* db; rocksdb::Options options; options.create_if_missing = true;

When the software exits, it prompts memory leaks.

Actual behavior

Steps to reproduce the behavior

Use VS2015 to create an MFC app. Add:

include <rocksdb/db.h>

rocksdb::DB* db; rocksdb::Options options; options.create_if_missing = true; rocksdb::Status s = rocksdb::DB::Open(options, "test", &db); delete db; Compile and run... on exit will show leaks

Version: rocksdb-6.0.2

Platform: Win7,x64

Compiler: VS2015,Win32

What objects are being leaked? Does it report a stack profile of those allocations?
