FreeRTOS on PIC 18F8722

I am trying the demo programs on a PIC 18F8722 on a CCS development board.
I have programs 1 and 2 (blinking LEDs) running, but the third (serial i/o)
resets on receiving serial input.  The problem appears to be in the task
switching within the serial ISR; if a character is received while the
input task is blocking on the queue, the program counter goes awry.

I have changed the amount of memory in the context save/restore functions
per the instructions on the web site, but nothing else related to context
or interrupts.

Can anyone offer help or suggestions on what to try next?
