            Bug ID: 103617
           Summary: Debugging gcc: can't use 'pp' command for irange
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: marxin at gcc dot gnu.org
                CC: dmalcolm at gcc dot gnu.org
  Target Milestone: ---

Using the GCC ./gcc/gdbinit.in:

define pp
eval "set $debug_arg = $%s", $argc ? "arg0" : ""
call debug ($debug_arg)
end

$ (gdb) p debug(predicate->true_range)
integer(kind=8) [-INF, 2147483646]

However:

(gdb) pp predicate->true_range
Attempt to take address of value not located in memory.

And the following works:

$ (gdb) pp &predicate->true_range
integer(kind=8) [-INF, 2147483646]
