Consider the following scenario, you have a Microsoft Windows Embedded CE 6.0 R2-based device that uses an ARM processor and that has the Microsoft .NET Compact Framework 3.5 installed. You attach the Just-In-Time (JIT) debugger to debug a managed application on the device. In this scenario, you receive a "Prefetch Abort" exception.
This problem occurs if the managed application's memory usage exceeds 32 MB. In this situation, the computed offset targets an incorrect branch of code to handle the breakpoints.
