            Bug ID: 15804
           Summary: pldd may leave process in stopped state
           Product: glibc
           Version: 2.17
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: schwab@linux-m68k.org
                CC: drepper.fsp at gmail dot com

There is a race condition that causes pldd to leave the process in stopped
state if the SIGSTOP signal that is implied by PTRACE_ATTACH isn't delivered
after the PTRACE_DETACH.  The tracer should always wait for the tracee to enter
ptrace-stop state before continuing to inspect it.
