= FIX: A Data Alignment Exception Occurs on a MIPS IV FP-Based System =

SYMPTOMS
When you end communication between a distributed component object model (DCOM) client and a remote procedure call (RPC) server on a MIPS IV FP microprocessor-based operating system, a data alignment exception may occur.

Additional attempts to connect to a remote DCOM server do not succeed until you reset the device.

Note This behavior does not occur on MIPS II or MIPS IV (non-FP) microprocessor-based operating systems.



CAUSE
This problem occurs because the OLE32/COM module contains code that accesses a data structure element that is not 64-byte aligned. On the MIPS IV FP microprocessor, this unaligned access causes an exception.



Hotfix Information
A supported software update is now available from Microsoft as Windows CE 4.1 Core OS QFE 830659. To resolve this problem immediately, click the following article number for information about obtaining Windows CE Platform Builder and core operating system software updates:
