    Hi,
   
   I am interested in defining a table dynamically in UPC.
This table should have affinity to Thread 0. I would like
to define an array like data1 below.
shared [] int data1[10][2];

   The way I did it is as follows:
shared [] int * shared [] * shared data2;
 
if (MYTHREAD == 0) {
      data2 = (shared [] int * shared [] *) upc_alloc(10 *
sizeof(int *));
      
      for(i = 0; i < 10; i++) {
	data2[i] = (shared [] int *) upc_alloc(2 * sizeof(int));
      }
}


Howevever when I use data1 in a gather it works fine
 upc_all_gather(data1, data, sizeof(int)*4,
UPC_IN_ALLSYNC|UPC_OUT_ALLSYNC);

Imagine that data in the gather above is defined as
shared [2] int data[10][2];


But when I use data2 in the same gather as bellow
 upc_all_gather(data2, data, sizeof(int)*4,
UPC_IN_ALLSYNC|UPC_OUT_ALLSYNC);

I get the following message:
UPC Runtime error: Attempt to use a bogus
upcr_pshared_ptr_t: addrfield out of range
  <pshared_ptr: addr=0xe2fed004 (offset=0x4), thread=0,
phase=0>
  at /UPC_DEBUG//include/upcr_sptr.h:1245

Any idea?

Kosta
