Is it Dtrace broken on HEAD?

Hello fellows,

Is it Dtrace broken on HEAD?

root_at_controllerB:/sys/amd64/conf # dtrace -n 'syscall::open*:entry {
printf("%s %s",execname,copyinstr(arg0)); }'
*dtrace: invalid probe specifier syscall::open*:entry { printf("%s
%s",execname,copyinstr(arg0)); }: "/usr/lib/dtrace/psinfo.d", line 37:
syntax error near "uid_t"*

root_at_controllerB:/sys/amd64/conf # uname -a
FreeBSD controllerB.la.com 10.0-CURRENT FreeBSD 10.0-CURRENT #0: Tue May 29
13:54:25 CST 2012     root_at_controllerB.la.com:/usr/obj/usr/src/sys/LA  amd64
