Thank you both,

I did a little research on gcc/driver bugzilla and it seepms my problem
might be ralated to those bug reports:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86030
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=45749 <- this one goes way
back to 2010 but it is still pending

Kind Regards,
Filip
