This bug was fixed in the package crash - 7.2.8-1ubuntu0.18.04.1
---------------
crash (7.2.8-1ubuntu0.18.04.1) bionic; urgency=medium
* Version bump from Focal, based on upstream release 7.2.8 (LP: #1865041):
- Multiple fixes up to kernel 5.5-rc1 (e.g., fixes for kmem/timer/log
commands, for kernels with symbol namespaces and with KASLR enabled).
- Improve handling of /proc/kcore (live memory) for x86_64 kernels with
CONFIG_RANDOMIZE_BASE enabled.
- Fix ARM64 page size handling on kernel 4.4 and before.
- Improve offset gathering and ELF support on KASLR kernels in S390X.
- Support xz compressed vmlinux.
- Fallback to log buffer parsing in case panic task can't be determined
by normal means in the dumpfile.
* Remaining changes:
- Update the maintainer field for Ubuntu.
- If the "live" autopkgtest fails with a recommendation to try
/proc/kcore instead of the default, attempt that before failing
the test. LP: #1858958.
* Fix test, as if will return 0 when no cases were true.

Title:
Bump crash version on Bionic and Eoan to match Focal
Status in crash package in Ubuntu:
Confirmed
Status in crash source package in Bionic:
Fix Released
Status in crash source package in Eoan:
Fix Released
Bug description:
[Impact]
* The crash tool aims to allow investigating kernel core dumps collected
through the kexec mechanism; as such, this tool is tightly coupled with kernel
version, needing awareness for example about kernel structs layout and other
kernel "API" details.
* Currently the crash tool is outdated in Bionic, not allowing users
to debug kernel core dumps collected with the latest HWE kernel
(version 5.3). Also, many bugs and improvements are added to crash as
newer kernels are released.
* This LP's goal is to bump the version of crash tool in both Bionic
and Eoan in order to match Focal version (7.2.8). With that we can
address the Bionic issue when opening kernel 5.3 dumps and gather more
fixes with the updated package.
[Test Case]
* The test performed is basically collect dumps with kdump-tools and open in
crash. In this particular case, the tests were with kernels 4.15.0-88 and
5.3.0-26 (in Bionic) and kernel 5.3.0-23 (in Eoan) using the crash tool built
with the hereby attached source.
[Regression Potential]
* Crash tool aims to have full retro-compatibility with kernel, so the
likelihood for regressions are low. If regressions are found, it's likely the
same regression applies to all crash/kernel pair versions, so by having the
package synced between releases we increase the exposure to gather more bug
reports and fix things in a more straightforward fashion.
NOTICE: This bump was agreed with Ubuntu kdump-tools/crash maintainer,
Thadeu Cascardo.
