Hello Mathis,

The project in the Github repository seems to be missing some CCS project metadata files (.ccsproject, .cproject). Could you please upload those as well? It will be easier for me to reproduce and investigate the issue if I have a complete project that I can import and build with CCS.

Sorry, i´ve created a new repository with the whole project.

you can find it here: https://github.com/mathisloge/comms-test-ccs-ti

Thanks for the help.

Thank you for sharing the project. I downloaded it and was able to reproduce the error but haven't had a chance yet to look into it further. I will file a bug report next week and then post an update here.

I filed this issue to be investigated further, the bug ID is CODEGEN-6581. Please feel free to track its status using the SDOWP link in my signature.

The segmentation fault occurs with -O0 and -O1, but does not occur with -Ooff, -O2 and -O3, so using a different optimization level could be a short-term workaround.

Thank you for bringing this to our attention.

Just a short update on this:

In a more complex setup the same seg fault happens at -Ooff, -O2 and -O3. So in this case the workaround doesnt resolve the issue

Unfortunately we don't have another reasonable workaround to suggest at the moment. Sorry about the inconvenience caused due to this.
