I'm using a rather old EPICS release (R3.12.0Beta1) and the problem
you are reporting has been corrected!

Just after entering the loop that goes for every record type,
and almost before doing anything else (certainly before calling
ellFirst()) there is a check:

                       .
                       .
                       .
    /* For every record type ... */
    for(i=0; i< (precHeader->number); i++) {
       /* Get pointer to location structure for instances of
          record type 'i' */
        if (!(precLoc = precHeader->papRecLoc[i]))continue;

        if (!precLoc->preclist) continue;
                       .
                       .
                       .

I think this solves the problem...
What release are you using?
