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.
