I found the bug in getFieldAddress:

         // FIELD in this record or VAL in other record
         char fullname[PVNAME_SZ + 1];
         sprintf(fullname, "%s.%s", name(), fieldname);
         if (dbNameToAddr(fullname, &dbaddr) != OK)
         {
             // VAL in other record
             sprintf(fullname, "%s.VAL", fieldname);
             if (dbNameToAddr(fullname, &dbaddr) != OK) return false;
         }

The first sprintf prints
$(device):StatEnable.$(device):StatEnableInterlock which is way too
long. My fault. I will send a patch soon....

Try this:
        // FIELD in this record or VAL in other record
        StreamBuffer fullname;
        fullname.print("%s.%s", name(), fieldname);
        if (dbNameToAddr(fullname(), &dbaddr) != OK)
        {
            // VAL in other record
            fullname.clear().print("%s.VAL", fieldname);
            if (dbNameToAddr(fullname(), &dbaddr) != OK) return false;
        }

(in src/StreamEpics.cc function getFieldAddress)
