>Description:
dtrace(1M) fails with the following error:

  # dtrace -n BEGIN 
  dtrace: invalid probe specifier BEGIN: "/usr/lib/dtrace/psinfo.d", line 46: syntax error near "u_int"

psinfo.d seems to contain syntax error(s). If I remove the file and try again, it works fine.
>How-To-Repeat:
modload dtrace
dtrace -n BEGIN

N/A
