I have tried to written small program and try to reproduce this issue but did not encounter any error.

#include<iostream>
#include "hpdf.h"
using namespace std;

class Report {
    public:
    HPDF_Doc document;
    HPDF_Page currentpage;
    void static error_handler (HPDF_STATUS,HPDF_STATUS,void *);
    void NextPage();
    Report(string, string, int);
    ~Report();
    string m_ReportFilePath;
};

void Report::NextPage()
{
    if (document == NULL)
    cerr << "(Report::NextPage) document is empty" << endl;

    currentpage = HPDF_AddPage(document);
    if (currentpage == NULL)
    cerr << "(Report::NextPage) current page is empty" << endl;
    cout<<currentpage<<"  "<<std::endl;
    HPDF_Page_SetWidth(currentpage, 595.3);
}

Report::Report(string fileName, string booktitle, int marg) {
    m_ReportFilePath = fileName;
    document = HPDF_New(Report::error_handler, &document);
    NextPage();         // Create new page
}

Report::~Report()
{
}

void Report::error_handler(HPDF_STATUS error_no,
               HPDF_STATUS detail_no, void *user_data)
{
    cout << "hPDF error error_no=" << (HPDF_UINT) error_no <<
    ", detail_no=" << (HPDF_UINT) detail_no << endl;
}

int main() {

    Report r("test.pdf", "test", 50);
    return 0;
}

issue when I compile on this machine

GDB output

Possible issue

currentpage = HPDF_AddPage(document);
if (currentpage == NULL)
logerror << "(Report::NextPage) current page is empty" << endl;
#value of currentpage is 0

The only time I've seen this error was when the PDF became so large it consumed all available memory. In my case, I was creating images using the PDF primitives (like a filled rectangle).

You really haven't given enough information to help diagnose the problem. Version of libHaru, 32 or 64 bit, generally what you are trying to do would be helpful.

Thanks for input @Bill H, lib_haru : 2.0.7 and gcc is 4.8.2 one strange thing, if I compile on Linux machine than I get else not – user765443 Jan 13 '21 at 10:02

I suggest you need to make the small program bigger until you can reproduce the problem, if still not clear post the code so we could investigate and comment.
