Please describe the problem:
Hello,

i have checked the sources of the current version of doxygen with the static code analyis tool cppcheck (http://sourceforge.net/apps/trac/cppcheck/wiki). I found a missmatch in the inheritance structure. A destructor of a base class is not declared as virtual. This can lead to memory leaks.

Steps to reproduce:
1. cppcheck -a -v -f -j2 -q doxygen-svn/src/
2. Output:
3. [src/docparser.h:168]: (error) Class CompAccept which is inherited by class DocHtmlTable does not have a virtual destructor
[src/docparser.h:168]: (error) Class CompAccept which is inherited by class DocSimpleSect does not have a virtual destructor



Actual results:


Expected results:
no error

Does this happen every time?
yes

Other information:
Take a look at file docparser.h:

[code]
template<class T> class CompAccept
{
  public:
    CompAccept() { m_children.setAutoDelete(TRUE); }
    void accept(T *obj, DocVisitor *v) 
    { 
      v->visitPre(obj); 
      QListIterator<DocNode> cli(m_children);
      DocNode *n;
      for (cli.toFirst();(n=cli.current());++cli) n->accept(v);
      v->visitPost(obj); 
    }
  
  protected:
    QList<DocNode> m_children;
};
[/code]

Indeed, it does not have a virtual destructor. This can easily avoided by declaring a virtual destructor:

	virtual ~CompAccept(){};
