Open serial port crashes program on device

[Steve]

I'm running AKU3.5 on a Sprint PPC6700 AKA the HTC Apache. When I run the GPS demo modded with my specific receiver's port number and baud rate, the app crashes once the serial port connection is open. I'm developing a GPS utility that uses the same component libraries as the demo, so there may be a conflict between the GPS and serial libraries in V5. I must also note that the GPS demo compiled and ran perfectly in V4. Since everyone here should have V5 installed by now, I'd appreciate any confirmation or denial of the bug. I haven't discounted the possibility that something is wrong on this new ROM I installed to my phone, though all other programs I use work fine.
Thanks and have a good day.
