Microsoft XML (MSXML) may experience random failures (access violations) when MSXML 4.0 Service Pack 1 (SP1) performs transforms on a free-threaded XML Document Object Model (DOM) document from multiple threads simultaneously. This problem is more likely to occur on multi-processor computers, and to occur under stress.
An internal part of the free-threaded XML DOM document is prematurely destroyed when MSXML 4.0 SP1 performs a transform. This issue occurs when MSXML cleans up a stack frame and, during this operation, uses a node attribute as a template parameter. Re-using this node may cause random failures because of the use of freed memory or the use of corrupted data.
