[Plib-users] Memory Leaks

[Alejo, L. W. <al...@ws...>]

Has anyone tried to incorporate plib into a MSVC++ MFC application?

I am in the process of developing an MFC application utilizing plib 
(mainly ssg) and the current snapshot of plib in cvs.sourceforge.net
produces a multiple number of memory leaks, as reported by BoundsChecker. 

I have made an attempt, on my version of plib, to squash a few of these
memory leaks and respectfully offer the following code changes to the
contributors of plib for consideration and inclusion into the library.

Changes:

In ssg.h:

virtual ~ssgLoaderOptions()
{ 
  if (model_dir)
  {
    delete model_dir;
    model_dir = 0;
  }

  if (texture_dir)
  {
    delete texture_dir;
    texture_dir = 0;
  }
}


In ssgTexture.cxx:

ssgTexture::~ssgTexture (void)
{
  if (filename != NULL)
  {
    delete [] filename;
    filename = NULL;
  }

  free_handle () ;
}


In ssgLoadSGI.cxx, added dtor:

ssgSGIHeader::~ssgSGIHeader(void)
{
  if (start != NULL)
    delete [] start;

  if (leng != NULL)
    delete [] leng;
}

I also discovered conflicting multiple definitions for macro _SSG_PUBLIC:
ssglocal.h:
#define _SSG_PUBLIC  public
 
ssg.h:
#ifndef _SSG_PUBLIC
#define _SSG_PUBLIC  protected
#endif
