I'm attaching a tarball with dmesg, the output of vmstat 1 that shows
the memory consumption during testing, and a copy of the test script
being used.

Title:
stress-ng triggering oomkiller running brk and stack stressors on all
arches.
Status in Stress-ng:
New
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Artful:
Confirmed
Bug description:
During regression testing on a z/VM instance, I noticed call traces
being dumped to dmesg that seem to be related to stress-ng.
The stress-ng invocation we're using is:
stress-ng --aggressive --verify --timeout $runtime \
--metrics-brief --tz --times \
--af-alg 0 --bsearch 0 --context 0 --cpu 0 \
--crypt 0 --hsearch 0 --longjmp 0 --lsearch
0 \
--matrix 0 --qsort 0 --str 0 --stream 0 \
--tsearch 0 --vecmath 0 --wcs 0
as executed by the cpu_stress script from the cpu/cpu_stress_ng test
in the certification suite.
