Hello,
numademo will crash if some options are added. For example, a simple
"numademo -c 20m memcpy" will cause a segmentation fault after memcpy
tests completed.
This issue has been there for long time as I can see it in both SuSE
and RHEL distros, and 2.0.2-rc2 package.
This patch fixes the segfault by adjusting variable ac to avoid array
index overflow.
