            Bug ID: 29053
           Summary: [m32] FAIL: gdb.fortran/lbound-ubound.exp: test 12:
                    check value of lbound ('array_1d_4bytes_overflow')
                    expression
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: fortran
          Assignee: unassigned at sourceware dot org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

With target board unix/-m32, I run into:
...
FAIL: gdb.fortran/lbound-ubound.exp: test 12: check value of lbound
('array_1d_4bytes_overflow') expression
FAIL: gdb.fortran/lbound-ubound.exp: test 12: check value of ubound
('array_1d_4bytes_overflow') expression
FAIL: gdb.fortran/lbound-ubound.exp: test 12: lbounds match
FAIL: gdb.fortran/lbound-ubound.exp: test 12: ubounds match
FAIL: gdb.fortran/lbound-ubound.exp: p lbound(array_1d_4bytes_overflow, 1, 8)
...

In more detail:
...
(gdb) p lbound (array_1d_4bytes_overflow)^M
$71 = (2147483644)^M
(gdb) FAIL: gdb.fortran/lbound-ubound.exp: test 12: check value of lbound
('array_1d_4bytes_overflow') expression
p ubound (array_1d_4bytes_overflow)^M
$72 = (-2147483637)^M
(gdb) FAIL: gdb.fortran/lbound-ubound.exp: test 12: check value of ubound
('array_1d_4bytes_overflow') expression
...

With native instead I get:
...
(gdb) p lbound (array_1d_4bytes_overflow)^M
$71 = (2147483644)^M
(gdb) PASS: gdb.fortran/lbound-ubound.exp: test 12: check value of lbound
('array_1d_4bytes_overflow') expression
p ubound (array_1d_4bytes_overflow)^M
$72 = (-2147483637)^M
(gdb) PASS: gdb.fortran/lbound-ubound.exp: test 12: check value of ubound
('array_1d_4bytes_overflow') expression
...

Hmm, that's the same output, so the difference is in the expected value.  Let's
annotate that in the test name:
...

        # Now ask for each bound in turn and check it against the
        # expected results.
...

That's a mismatch indeed:
...
