access violation using wxTreeCtrl

[Harry]

Vadim,

Using Visual Studio 2005 and daily build wxMSW-2008-03-04, I don't get 
the assertions,
but I still get the abort:
  Unhandled exception at 0x74cdc1f4 in treectrl.exe: 0xC0000005: Access 
violation reading location 0xfeeeff0a.
It seems to me like wxTreeCtrl::DeleteAllItems() is trying to delete 
already-deleted items.
The difference between your findings and mine might be because of racing 
conditions caused by
differences between our respective machines.
If you point me out in the right direction I can continue to debug this 
on my machine, or else as we're both
in france we can get in direct contact.

The stack trace is as follows:
