+- DosQuerySysState bug when object information is requested. Probably a
+  problem which occurs in _LDRSysMteInfo when qsCheckCache is calle before
+  writing object info. The result is that the cache flushed and the attempt
+  of updating the qsLrec_t next and object pointer is not done. This used to
+  work earlier and on Aurora AFAIK.
+
+  The fix for this problem is to check if the pObjInfo is NULL while the
+  number of objects isn't 0 and correct this. pNextRec will also be NULL at
+  this time. This will be have to corrected before we exit the loop or moves
+  to the next record. There is also a nasty alignment of the object info...
+  Hope I got it right. (This aligment seems new to FP13.)
