Hey,



Here are the lines:
    178 void SwBlink::FrmDelete( const SwRootFrm* pRoot )
    179 {
    180     for( SwBlinkList::iterator it = aList.begin(); it !=
aList.end(); )
    181     {
    182         if( pRoot == (*it).GetRootFrm() )
    183             aList.erase( it );
    184         else
    185             ++it;
    186     }
    187 }

I must recognize, I don't understand how can it work above all if we go  in
the "if" since there's no increment.

Any idea?

It can't. Line 183 is supposed to be:

aList.erase(it++);


No, it should be
   it = aList.erase(it);

Once you have called erase(), the iterator becomes invalid, so it must
be replaced by the iterator returned by erase(), which returns the
next valid position,
