Image relocation logic problems...

....under BeOS...
  
I get thru the initializeFirstFreeMemory routine ok and then once I get into 
the core of InitializeInterpreter I trap out when I try to execute:
 nilObj = longAt(((((char *) specialObjectsOop)) + 4) + (0 << 2));

under BeOS specialObjectsOop = 2094925144 (which is the value 
of bytesToShift).  bytesToShift = startOfMemory() - oldBaseAddr where
startOfMemory = 2147553280 under BeOS (0x80011000).
oldBaseAddr = 52628136 read from the image and matches the the value I get 
on the Mac.


I've waded thru the code and don't see any problems in the logic 
but apparently the longAt bombs out (with an "Unknown PPC exception).  longAt is 
#define longAt(i) (*((int *) (i)))

and I've tried longAt(i) (*((uint32 *)(i)))
and I've tried redifining specialObjectsOop from int to uint32 as well.


I need another pair of eyes...anyone see anything screwy?
thanks,
Serg
