--- Comment #2 from gpmfuchs at gmx dot de ---
I've run repeatedly into this bug.
My use case is a c++-program which forks whenever an assert is hit or a
watch-timer is triggered, then it redirects stdout/stderr to a tmpfile and
execl to gdb, in order to get a bug report.
The bug means in my case, that gdb fills it's tmpfile with
"linux_check_ptrace_features: failed to kill child" until the /tmp mount is
full.
Which means it starves the autotest-system of memory, triggering random
OOM-kills, and as a result crashing the autobuild-system.
