Hi.

 

I'm using tifflib version 3.1.6. There is an apparent memory leak in the 
library.

I wrote a simple program to open and close a tiff file in a loop and watched
the memory increase gradually.

Here is the program written as a console app in VS C++ 6.0.

// TiffTest.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include "TiffTest.h"
#include "tiffio.h"
#include "direct.h"
 
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

CWinApp theApp;

using namespace std;

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
            // initialize MFC and print and error on failure
            if (!AfxWinInit(::GetModuleHandle(NULL), NULL,
::GetCommandLine(), 0))
            {
                        // TODO: change error code to suit your needs
                        cerr << _T("Fatal Error: MFC initialization failed")
<< endl;
                        return 1;
            }
            char exeFilePath[MAX_PATH];
            char drive[_MAX_DRIVE];
            char dir[_MAX_DIR];
            char fname[_MAX_FNAME];
            char ext[_MAX_EXT];
            CString strFilePath;
            // get the exe file name
            GetModuleFileName(0, exeFilePath, MAX_PATH);
            _splitpath(exeFilePath, drive, dir, fname, ext);
            strFilePath.Format("%s%s%s", drive, dir, "FILES");
            _mkdir((LPCTSTR)strFilePath);

            strFilePath += "\\CHECK.TIF";

            TIFF *image;

            for (int i = 1; i < 100000; i++) {
                        //Open the TIFF Image
                        if((image = TIFFOpen(strFilePath, "rM")) == NULL) {
                                    printf("Error in opening TIFF\n");
                                    break;
                        }           
                        TIFFClose(image);
                        image = NULL;
            }

            return 0;
