TIClang compiler generates an error for a missing .opt file, but this error's text does not match any of the compiler error parser's regex'es, so it does not generate an error marker.

1. Create any ARM TIClang project
2. Open project Properties, then on page Build > Tools > Compiler > Advanced Options > Command Files, add a non-existent .opt file to the list
3. Build the project
4. -> The missing .opt file generates an error in the build-output
5. -> The error is coloured in red in Output view
6. -> But it does not show up in the Problems view
