            Bug ID: 27989
           Summary: gdb.base/args.exp fails with native-extended-gdbserver
                    board
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: simark at simark dot ca
  Target Milestone: ---

It boils down to this.  With native:

$ ./gdb -nx -q --data-directory=3Ddata-directory \
    -ex r \
    --args
/home/smarchi/build/binutils-gdb/gdb/testsuite/outputs/gdb.base/args/args s=
alut
"''" toi

produces:

salut
''
toi


With extended-remote (with a gdbserver --multi listening on 1234):

$ ./gdb -nx -q --data-directory=3Ddata-directory \
    -ex "tar ext :1234" \
    -ex "set remote exec-file
/home/smarchi/build/binutils-gdb/gdb/testsuite/outputs/gdb.base/args/args" \
    -ex "set sysroot" \
    -ex r \
    --args
/home/smarchi/build/binutils-gdb/gdb/testsuite/outputs/gdb.base/args/args s=
alut
"''" toi

produces:

salut
\'\'
toi


I have not dug more than that, but I think that shows a bug in the
extended-remote version.  Here, I want to literally pass
<single-quote><single-quote> as the argument to my program, such that

  strcmp ("''", argv[2]) =3D=3D 0

--=20
