It seems that's what caused the verification to fail for bug 1732865. The following fixes have been committed upstream: from 2.30: https://github.com/karelzak/util- linux/commit/0145d84a381fc2fcd7d37e0dbf3d9dff69609ecd from 2.32: https://github.com/karelzak/util- linux/commit/95f09bc63c564c50ec2c393352801cc056faaea2 I plan to backport them to xenial (both patches); and artful, bionic (second patch, they are > 2.30). [Regression potential] The worst possible regression is that lscpu would fail to correctly report min/max frequencies, but it seems unlikely, as we're only adding checks against null pointers / move an atof into a loop. [Test case] Extract attached segvtest.tar.gz and run lscpu -s segvtest and check that it does not crash (this removes min mhz file for cpu #0 for testing).
