SYMPTOMS

When you compile Microsoft intermediate language (MSIL) code into an executable program in release mode in the Microsoft .NET Framework 2.0, you may receive an "IndexOutOfRangeException" error message.

This problem does not occur when you compile MSIL code into an executable program in debug mode.

CAUSE

This problem occurs because of an optimization bug in the just-in-time (JIT) compiler in release mode.
