APPLIES TO
- Microsoft Windows CE .NET 4.1
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.
RESOLUTION
