I am trying to build CRTM from the main repository but the make check fails for CrIS KMatrix as follows: ``` Initializing the CRTM... ``` Loading Spc file.

Hello Isaac. I can have a look at it. Could you first check if it’s a stack size issue with ```auto $ ulimit -s unlimited ``` And then re-run the test? ---

Thanks, Patrick. It didn’t solve it, still the same issue.
