Introduction

This article describes an issue in which calling code in the unwind.cpp file causes an application to crash in Windows Embedded Compact 7. An update is available to resolve this issue. Before you install this update, all previously issued updates for this product must be installed.

Symptoms

When you call the following code in the Unwind.cpp file in a Windows Embedded Compact 7 application, the address reference that is generated in the code (Address = READ_DATA_ULONG(ProcessId, Register[RegIndex] + (Opcode & 0xfff));) points to an invalid address area and causes the application to crash.

Unwind.cpp code

static BOOL ArmWalkEpilog(
__in ULONG PrologBeginAddress,
__in ULONG EpilogPc,
__in ULONG MaxEpilogBytes,
__in CONTEXT * ContextRecord,
__in PROCESSID_T ProcessId
)
