28   zero.  If SUBSTITUTION_NAME is not NULL, then a reference to this
29   decl in the source will later be substituted with a dereference

31   an address (e.g., functions), ADDRESS is the address.  FILENAME
32   and LINE_NUMBER refer to the symbol's source location.  If this
33   is not known, FILENAME can be NULL and LINE_NUMBER can be 0.
