CCS/TMS320DM6437: Strange compiler error

Part Number: TMS320DM6437

Tool/software: Code Composer Studio

Have got that compiler error using Code Composer Studio 5.5 and CGT v7.4.4:

>> ERROR: Bad tag:

>> Compilation failure
'Invoking: C6000 Compiler'
gmake: *** [source_file.obj] Error 1

which isnt colored in red. So overall compilation is also failed. But if i run compiling again (not cleaning project) it will success.

    That is odd that is succeeds during the second build.

    Is this the only error that is output in the build console? Could you do a Rebuild Project, then save the full output of the CCS build console to a text file (as described here) and attach the log here?

    Yes, it is the only error.

    Also, if i build the only problem file I always see that error. 

    About build console, it consist of standard compiler output for every source file in project without any errors except problem file.

    "Problem" file is ok from c++ point of view. It well tested and written earlier (and not by me).

    Forgot compiler options:

    'Invoking: C6000 Compiler'
    "C:/ti/ccsv5/tools/compiler/c6000_7.4.4/bin/cl6x" -mv64+ --abi=coffabi -O3 -ms3 -g --include_path="C:/ti/ccsv5/tools/compiler/c6000_7.4.4/include" --include_path="C:/" --include_path="C:/ti/sdo/pspdrivers/soc/dm6437/dsp" --include_path="C:/ti/bios_5_42_01_09/packages/ti/bios/include" --include_path="C:/ti/bios_5_42_01_09/packages/ti/rtdx/include/c6000" --define=dm6437 --diag_error=225 --consultant --fp_not_associative --fp_reassoc=off --debug_software_pipeline --opt_for_speed=5 --fp_mode=relaxed --asm_listing --preproc_with_compile

    I searched through some internal reports and it appears the error may be due to the --consultant option. That option is actually not supported in the 7.4.x compiler.  It is replaced by the option --advice:performance.  Please read about it in the section titled Using Performance Advice to Optimize Your Code in the C6000 compiler manual.  

    If you remove that option or replace it with --advice:performance the error should go away.
