setsppfp crashes with MCH6801

Hi,

I have a program that utilizes setsppfp() to get a pointer to the associated 
space of a binding
directory object. It runs fine on our development box as well as on our 
production box. The program
crashes with MCH6801 on our test box which is another LPAR of our production 
box. The violation type
is 1 = Object domain violation.

Both LPARS (production and test) are at security level 30. As far as I know the 
production LPAR is
DBCS and the test LPAR is SBCS. Both LPARs are at PTF level TL05298.

This is the code I use:

 *
D pObj            S               *   inz  procptr
D spcObj          S          32767A   based(pSpcObj )
 *
 *  Resolve system pointer to object

C                   Eval      pObj = rslvsp(WLI_BNDDIR  :
C                                           obj_name    :
C                                           obj_lib     :
C                                           AUTH_SPACE  )
 *
 *  Get space pointer from system pointer
C                   Eval      pSpcObj = setsppfp(pObj)
 *
 *  Since we can not access the data of the associated space
 *  directly, we have to copy it from the system domain to the user domain.
 *  (We do not really want to patch the program to system state.  ;-)  )


Any help would be greatly appreciated.
