Public bug reported:
There is a known issue in strace, where attaching to children fails due
to races in strace code. See [1] for description of the bug on strace
developer mailing list. A patch [2] was created 2013-07-08 to fix the
problem. The problem might also occur when debugging real-world
applications, thus obscuring the real cause of a problem, e.g. in [3].
