Why should these get a CVE? As you state in one of your reports:
While I appreciate that passing untrusted code to gawk is not a
common thing to do, I do not believe that it should be possible to
trigger a segfault though.
Why should that be considered a valid / safe use case at all? If
something makes awk run untrusted programs, there's code execution
problem already:
echo | awk '{ system("id") }'
