CCS/LAUNCHXL-F280049C: Segmentation fault in CCSv10, Compiled successfully in CCSv9

Tool/software: Code Composer Studio

Hi,

I am experiencing a segmentation fault in CCSv10. After initial diagnose, the problem is found to be with the function pointer. The same code compiled without errors in CCSv9.

The function pointer causing the problem is:

(*SchedulerTasks[Ctr].TaskAddress)();

CCS Version: 10.0.0.00010

Below is the error message:

This is caused by a defect in the TI C/C++ Parser.
TI Customer Support may be able to suggest a workaround to avoid this.

Upgrading to the newest version of the compiler may fix this problem.

Contact TI in the E2E support forums at http://e2e.ti.com under
"Development Tools", "TI C/C++ Compiler". See the link titled
"Submitting an issue".

We need to see this ENTIRE error message and a complete, reproducible
