QHash and pointers - how to clear correctly

[roxton]

Hello!
I have the permanent segfault when I try to manually delete pointers from my hash table.
Here is some code.

This is the class that I use as hash table value:

class CMarkupPair: public QObject
{
  Q_OBJECT
 
public:
 
  QHash <QString, QString> pattern;
};

class CMarkupPair: public QObject
{
  Q_OBJECT

public:

  QHash <QString, QString> pattern;
};

To copy to clipboard, switch view to plain text mode 

And thats my table:

QHash <QString, CMarkupPair*> hs_markup;

QHash <QString, CMarkupPair*> hs_markup;

To copy to clipboard, switch view to plain text mode 

I tried many ways to delete values from here. For example:

QList<CMarkupPair *> l = hs_markup.values();
foreach (CMarkupPair *p, l)
          delete p;

QList<CMarkupPair *> l = hs_markup.values();
foreach (CMarkupPair *p, l)
          delete p;

To copy to clipboard, switch view to plain text mode 

Or, even worse:

QList <QString> hs_markup_keys = hs_markup.keys();
 
foreach (QString key, hs_markup_keys)
          {
           CMarkupPair *p = hs_markup.take (key);  
           delete p;
          }

QList <QString> hs_markup_keys = hs_markup.keys();
  
foreach (QString key, hs_markup_keys)
          {
           CMarkupPair *p = hs_markup.take (key);  
           delete p;
          }

To copy to clipboard, switch view to plain text mode 

And when I try to "delete p", I have the segfault. My "p" is not NULL, it's ok pointer. Please help
