An access violation may occur in the Microsoft XML (MSXML) 3.0 parser when you format XML with long attribute values.
The
IXMLNodeFactory interface reports the size of the attribute list by using a
USHORT argument. The access violation occurs because the
USHORT argument overflows when the attribute values are too long.

HOW TO: Upgrade the Microsoft XML Parser
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
Because this bug is in a published public interface, Microsoft cannot produce a complete fix. The hotfix described in the "Workaround" section of this article avoids the access violation because it aborts the parse and returns E_FAIL when it detects a potential "crash" situation.
