Grasping at straws here - but are you sure it is still a valid pointer? If
the area of memory containing the pointer was written by anything other than
a pointer instruction, the contents of the pointer memory may be unchanged,
but the tag bit will have been reset and so the pointer would no longer be
valid.

I just did one of those. STRDBG shows the value of the invalidated
pointer as SPP:*NULL.

The program is ...
0005.00 D x s 1a
0006.00 D thing ds
0007.00 D p *
0008.00 D smasher 10i 0 overlay( p : 1 )
0009.00 /free
0010.00
0011.00 // make a good pointer
0012.00 p = %addr( x );
0013.00 // what does strdbg show?
0014.00
0015.00 // destroy the pointer, presumably
0016.00 smasher = smasher;
0017.00 // what does strdbg show?
0018.00
0019.00 *inlr = *on;

Cheers,
Terry.
