global protection fault in module cvirte.dll

Hi,

My program has a treeview in which I have to insert items.The datas come from a XML file. I use the libxml2.lib.

When I want to load the new XML file in the treeview, I get sometimes a General Protection Fault in cvirte.dll, which crashes the whole program.

In debug mode, it crashes at the same line, when I use the function InsertTreeItem.

Any ideas where to look for the problem would be appreciated.

Thanks.
