FIX: An application that performs an XSLT transformation may cause an access violation in the Microsoft XML 3.0 parser (919587)


The information in this article applies to:

  • Microsoft XML 3.0
Bug #: 795 (SQL Hotfix)

SYMPTOMS

When an application performs an XSLT transform by using Microsoft XML (MSXML) 3.0, the application may cause an access violation in the MSXML 3.0 parser.

CAUSE

This problem occurs because the Microsoft XML 3.0 parser does not correctly add reference entries that are added to a hash table. This behavior can cause a crash if the garbage collector frees the reference entries before the entries are used.

RESOLUTION

A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next Microsoft XML 3.0 service pack that contains this hotfix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the hotfix. For a complete list of Microsoft Product Support Services telephone numbers and information about support costs, visit the following Microsoft Web site:

The usual support costs will apply to additional support questions and issues that do not qualify for the specific update in question.
