Two things to look at:
 * On the MBX (PowerPC especially), disable the option 
   CYGDBG_HAL_COMMON_CONTEXT_SAVE_MINIMUM as this is known to 
   confuse GDB [sometimes].
 * The message above looks like you were trying to watch a variable's
   "value" not location.  Just make sure you specify the watch carefully.

Hope it helps.
