NGen introduces instability

We have a section of code that executes cleanly until that code is
NGen'ed. After a native image has been created, that same section of
code produces a .NET Runtime Fatal Execution Engine Failure and the
application closes without warning.

Here is the error for the Event Viewer: .NET Runtime version
2.0.50727.42 - Fatal Execution Engine Error (7A05E2B3) (80131506)

We've re-created this issue on XP, Win2000, and Win2003. We've executed
the native image in the debugger; however the debugger does not produce
anything insightful.

Has anyone else encountered this?

Thank you for your time,
Bill O'Neill
