Java SWIG wrapper vs direct function calling

I have some kind of library that I am writing wrapper for and then I am trying to generate SWIG wrapper on it so I could make calls straight from Java.

I encountered a problem which I can not debug as there are basically 0 information (Java side). Here is what I am dealing with. I have got a custom class like this:

class APIClass {

private:

public:
    APIClass();
    void mbstowcsTest();
};

And its implementation looks like this

typedef unsigned short      AName[32];

void APIClass::mbstowcsTest() {
  const char* source = "D:\\test3\\source\\test.txt";
  AName tmp1;
  mbstowcs((wchar_t*)tmp1, source, 32 - 1);
}

With such code I am generating SWIG files for it and compile the code with batch script like so:

@echo off
call "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat" x64

swig -c++ -java -outdir java api.i

set CompilerFlags=-nologo -Zi
pushd build
cl %CompilerFlags% ..\api.cpp ..\api_wrap.cxx /I"C:\Program Files (x86)\Java\openjdk8u102-win_jdk\include"^
  /I"C:\Program Files (x86)\Java\openjdk8u102-win_jdk\include\win32" /LD /EHsc
popd

COPY .\build\api.dll .\java\

As for api.i interface file it is only:

%module api
%{
    #include "api.h"
%}
%include "api.h"

Basically, if I am calling APIClass::mbstowcsTest() in the C++ main function all is going well and mbstowcs() is going through without any problems like so:

APIClass *api = NULL;
api = new APIClass();
api->mbstowcsTest();

While in Java side I have:

class main {
    public static void main(String[] args) {
        System.loadLibrary("api");
        APIClass api = new APIClass();
        api.mbstowcsTest();
    }
}

The problem in Java code is that whenever code reaches mbstowcs() in APIClass::mbstowcsTest() all I am getting is outputs like Process finished with exit code -1073740791 (0xC0000409). Could anyone tell me why is that a problem? I tried using other functions from stdlib.h like abs() and it worked.

Turned out that it is essential to use the same compiler flags as in Visual Studio 2013 compilation. Therefore the batch script should look at least as:

@echo off
call "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat" x64

swig -c++ -java -outdir java api.i

set CompilerFlags= /Zi /nologo /W3 /WX- /sdl /Od /Oy-^
    /D WIN32 /D _DEBUG /D _CONSOLE /D _LIB /D _CRT_SECURE_NO_WARNINGS /D _CRT_SECURE_NO_DEPRECATE^
    /D _UNICODE /D UNICODE^
    /Gm /EHsc /RTC1 /MDd /GS /fp:precise /Zc:wchar_t /Zc:forScope /Gd /LD

pushd build
cl %CompilerFlags% ..\api.cpp ..\api_wrap.cxx /I"C:\Program Files (x86)\Java\openjdk8u102-win_jdk\include"^
  /I"C:\Program Files (x86)\Java\openjdk8u102-win_jdk\include\win32"
popd

COPY .\build\api.dll .\java\

Now everything works just as fine
