The asmgcc gcrootfinder, which was the default until recently, doesn't work with Clang. You need to pass --gcrootfinder=shadowstack as an RPython option. RPython options are passed in here between -mrpython and main.py: https://github.com/monte-language/typhon/blob/9dffc61cccfc1a114d58615f65f696bb69075f32/nix-support/vm.nix#L46
