FreeBSD recently increased the size of cpuset_t from 256 to 1024, encoded in the macro CPU_MAXSIZE which you get if you include <sys/cpuset.h>. This is only in the latest development version of FreeBSD 14. It is not in any released version.

This fixes the compilation error. I have not tested the resulting sanitizer libraries.
