This is caused by a defect in the TI C/C++ Optimizer.
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
test case including ALL of the command-line options.
Include the .pp file created by option --preproc_with_comment

Used compiler is: ti-cgt-c7000_3.1.0.LTS

CCS project generating the internal error is attached.

v_fix_point_opt_fail.zip

I’ve found out that the internal error disappears if “non-class” template functions are used instead of static methods of template class. Those options can be switched by changing of "#if 0" at line 28 of v_fix_point_hypot.h to "#if 1".
