            Bug ID: 30373
           Summary: Random? failure of "p_align-1b with PIE" and
                    "p_align-1d with -Wl,-z,max-page-size=0x1000 with PIE"
           Product: binutils
           Version: 2.41 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: clyon at gcc dot gnu.org
  Target Milestone: ---

In our x86_64 native CI loop, I have noticed that
ld-elf/linux-x86.exp
FAIL: Run p_align-1b with PIE
FAIL: Run p_align-1d with -Wl,-z,max-page-size=0x1000 with PIE

happen apparently randomly :-(

I have tried to reproduce it manually with no luck, however when executing the
test binary under valgrind I get this:

in ld.log, I can see:
Running: tmpdir/p_align-1b > tmpdir/p_align-1b.out
child killed: SIGABRT
FAIL: Run p_align-1b with PIE

Running: tmpdir/p_align-1d > tmpdir/p_align-1d.out
child killed: SIGABRT
FAIL: Run p_align-1d with -Wl,-z,max-page-size=0x1000 with PIE
