[Magick-bugs] It seems there is a memory leak.

[Evgeny Rippi]

Hi ImageMagick users,

I created a small program and intentionally added an exception
situation. I'm using ImageMagick that is set to use the Windows
registry. I have changed the registry record from Q:8 to Q:81, as such
ImageMagick can not work properly because it can not find the modules.
I've created the loop where I convert the image. And the exception
occurs in the Image()
constructor.

The code:

#include <Magick++.h>

using namespace std;
using namespace Magick;

namespace EngineR
{

namespace Converter
{
	Blob result;
	std::string errorMessage;

	int Convert(void* data, int length,
		pConstVoid& convData, int &width, int &height, int& convLength)
	{
		try
		{
			Blob blob(data, length);
			Magick::Image image(blob);  // in this point the exception occurs:
"ImageMagick: RegistryKeyLookupFailed `CoderModulesPath'"

			// write data
			image.write(&result, "JPG");
			convData = result.data();
			convLength = result.length();

			// image dimensions
			width = image.size().width();
			height = image.size().height();

			return 0;
		}
		catch( Magick::Error &error )
		{
			errorMessage = error.what();   // then it comes here
			return 1;
		}
		catch( std::exception &error )
		{
			errorMessage = error.what();
			return 1;
		}
		catch(...)
		{
			errorMessage = "unknown error occured";
			return 1;
		}
	}

	const char* GetLastErrorDescription()
	{
		return errorMessage.c_str();
	}

};

};

#include <iostream>
#include <fstream>
using namespace std;

void main()
{

	ifstream file ("dsc.jpg", ios::in|ios::binary|ios::ate);

	ifstream::pos_type size;
	char * memblock;
	const void* convData;
	int convLength;
	int width, height;

        // open the file to be converted
	if (file.is_open())
	{
		size = file.tellg();
		memblock = new char [size];
		file.seekg (0, ios::beg);
		file.read (memblock, size);
		file.close();
	}

	for (int i=0; i<100000; i++)
	{
		EngineR::Converter::Convert(memblock, size, convData, convLength,
width, height);

		std::cout << "i=" << i << std::endl;
	}

}

So, the memory a little leaks during the iterations as it shows
windows task manager.

Please, check it out is it really a bug or I missed something out?
