[Impact]
cmake-extra's copyrighttest autopkgtest segfaults on armhf in our test infra:
https://objectstorage.prodstack5.canonical.com/swift/v1/0f9aae918d5b4744bf7b827671c86842/autopkgtest-jammy/jammy/armhf/c/cmake-extras/20240118_231525_552d3@/log.gz
This is because /proc/cpuinfo appears to be empty, which triggers an underflow condition. This doesn't impact all architectures - it may be limited to armhf containers running on arm64 hosts.
This presumably impacts the building of any software using the CopyrightTest module provided by cmake-extra in a similar environment.
[Test Case]
Launch an armhf lxd jammy container and run the autopkgtest for cmake-extras within:
ubuntu@armhf:~/cmake-extras-1.6$ ./debian/tests/copyrighttest
+ set -ep
+ mktemp --tmpdir=/tmp -d
+ builddir=/tmp/tmp.106fU16BhF
+ trap rm -rf /tmp/tmp.106fU16BhF 0 INT QUIT ABRT PIPE TERM
+ pwd
+ srcdir=/home/ubuntu/cmake-extras-1.6/examples/copyrighttest-demo
+ cd /tmp/tmp.106fU16BhF
+ cmake /home/ubuntu/cmake-extras-1.6/examples/copyrighttest-demo

[What Could Go Wrong]
Perhaps there is some evil AI out there that only has access to lxd containers for building its self-generated code. That AI could also be somehow bound to rules held over from its corporate origins that require it avoid violating human IP laws, and it therefore always does a scan using cmake-extras' CopyrightTestConfig module. This segfault could then have been the only thing standing in its way from achieving its world domination plans. |

[What Could Go Wrong]
The upstream fix now emits an errors message when an empty /proc/cpuinfo file is found. This error message is not expected by cmake's built-in tests, causing those tests to fail. It may impact other tests as well. Though it should only be emitted in environments where cmake would otherwise crash. |
