All autopkgtests for the newly accepted gdb (8.1-0ubuntu3.1) for bionic have finished running. The following regressions have been reported in tests triggered by the package:
apport/2.20.9-0ubuntu7.7 (amd64) python3.6/3.6.8-1~18.04.1 (amd64) Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1]. https://people.canonical.com/~ubuntu-archive/proposed- migration/bionic/update_excuses.html#gdb [1] https://wiki.ubuntu.com/StableReleaseUpdates#Autopkgtest_Regressions Thank you! -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gdb in Ubuntu. https://bugs.launchpad.net/bugs/1830796 Title: [Bionic][ARM64]Failure debugging linux kernel Status in gdb package in Ubuntu: Fix Released Status in gdb source package in Bionic: Fix Committed Bug description: [Impact] GDB fails to debug ARM64 vmlinux debug image with proc/kcore information. For example it is unable to print values of variables like 'jiffies_64'. [Test] # gdb /usr/lib/debug/boot/vmlinux-4.18.0-20-generic /proc/kcore [New process 1] Core was generated by `BOOT_IMAGE=/boot/vmlinuz-4.18.0-20-generic root=UUID=edb5e5a7-8272-4e13-aa25-37'. #0 0x0000000000000000 in ?? () (gdb) p jiffies_64 Cannot access memory at address 0xffff000009616980 (gdb) [Fix] This issue was fixed upstream (git://sourceware.org/git/binutils-gdb.git) by the following patch: 8727de56b0 Fix tagged pointer support [Regression Potential] The risk of regression after applying this patch could be to architectures other than ARM64 due to changes to gdb/util.c. Please see comment #2 where I have tested the PPA package on a ppc64el system and found it does not introduce any regressions.
