"Compilation stopped. Internal failure occurred. Error Code is 1."

Here's the full source of a failing test program:

fPATMST    if   e           k disk    prefix('PT.')
dPT             e ds                  extname(patmst) qualified

 /free
  if PT.PAGE > 65;
    *inlr = *inlr;
  endif;
  *inlr = *on;
 /end-free

The compile is failing at this point:

    65=IPTREC
        *--------------------------------------------------------
        * Data structure . . . . . . :  PT
        * External format  . . . . . :  PTREC : FILES/PATMST
        * Format text  . . . . . . . :  PATIENT MASTER
        *--------------------------------------------------------
<snipped several fields>
    74=I                             P   48   49 0PT.PAGE

(there are other fields after this one defined in the file, but the 
compile stops at this field)


This is the error message on the compile listing:

Compilation stopped. Internal failure occurred. Error code is 1.


Am I missing a PTF?
