    • Don't put a function pointer into a struct in CLA code.
    • Hide
      Function pointers are not allowed in CLA code. When encountered, the compiler should issue a diagnostic. However, if the function pointer is a field in a struct, the compiler may crash instead. It still indicates that a function pointer may not be used, but it's unclear and shouldn't happen that way.

      Use the attached files. The file try1.cla contains these lines ...

      struct TestStruct
{
    void (*FunPtr)(void);
};

/* Many lines later, inside a background task function */
        Test.FunPtr();

      Build it ...

      % cl2000 -@options.txt try1.cla

INTERNAL ERROR: accla experienced a segmentation fault

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
test case including ALL of the command-line options.

>> Compilation failure

      In the subset of C supported by the CLA compiler, functions pointers are not supported. Neither are functions calls from background tasks. Even so, the compiler should emit diagnostics and complete normal execution.
