[Valgrind-users] Ghostly bug from Spain. Help!!!

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hi! I=B4m a slight developer from spain... but
I'm sure The Valgrind Proyect is a universal "key" achievement for the
free (and not free!) developers community. I=B4m very happy with the
tool. It=B4s simply amazing.

Thanks!

However I have a very terrible and strange trouble. Yes!. Terrible and stra=
nge.

Ok! I'm developing with gcc C++ and ImageMagick 6.2.5 libraries in
Fedora Core 4 environment.

(Valgrind 3.1.0 version)(Valgrind 2.4.1 version)

A very simple program...

------------------------------------------------------

#include <Magick++.h>
#include <iostream>
using namespace std;
using namespace Magick;
int main(int argc,char **argv)
{
  // Construct the image object. Seperating image construction from the
  // the read operation ensures that a failure to read the image file
  // doesn't render the image object useless.
  Image image;

  try {
    // Read a file into image object
    image.read( "Frame--0000.bmp" );

  }
  catch( Exception &error_ )
    {
      cout << "Caught exception: " << error_.what() << endl;
      return 1;
    }
  return 0;
}

---------------------------------------

I launch Valgrind memcheck with...

valgrind --tool=3Dmemcheck -v --leak-check=3Dfull --log-file=3DTRAZA
./imagemagick-valgrind

and I wait...and wait...and wait.... Valgrind is frozen, shocked,
deadlocked? I don=B4t know.

Ctrl+C and here is the log:

Ok! What is the strange?

This sample...(and my source of ten thousand codelines) was beaten by
Valgrind without any trouble. One, two, three... a hundred times...
but, suddenly! Imagemagick "reads" freeze Valgrind.

I have uninstalled Valgrind completely... and I have uninstalled
ImageMagick completely.
After that, I have configured, maked and installed Valgrind and
ImageMagick without troubles... but... my weak efforts are futile.

In anothers computers (with FC4) the trouble is reproduced. At the
beginning there are not any trouble... but suddenly, the problem go
back in just a very few weeks. Sigh!!!

I'm frustrated. Any idea? Any question? Thanks in advance. I=B4m sorry
for my abominable english.
