            Bug ID: 25650
           Summary: GDB can't 'printf' a convenience variable holding an
                    inferior address
           Product: gdb
           Version: 9.1
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: sergiodj at redhat dot com
  Target Milestone: ---

This is a regression from 8.3.

When assigning an inferior address to a convenience variable, GDB is unable=
 to
print it correctly.  It's possible to reproduce this bug by doing:

$ echo -e 'int main(){const char a[]=3D"test";return 0;}' | gcc -x c - -O0-=
g3
$ ./gdb/gdb --data-directory ./gdb/data-directory -q ./a.out -ex 'start' -ex
'set $x =3D (const char *) (&a[0] + 2)' -ex 'printf "%s\n", $x'

This has been fixed upstream; I'm creating this bug to backport the fix to =
the
9.1 branch.
