I just checked that project from GitHub, and I don't have that problem.
But the file name and error let me believe this is something inside the Processor Expert files, and somehow they are screwed up? Did you made an update or change to your installation recently?
Can you check what your about box says? I have
- CodeWarrior for MCU
Version: 10.3
Build Id:121211
I'm aware that there was an update on the web for a short period of time which has a problem: if you perform the update while you are debugging (or if you had a debug session right before the update), then this could have corrupted your installation.
Not sure if this is your problem.
