Bug#985645: hurd: Hurd creates buggy core files or gdb cannot read core files properly
Source: hurd
Version: 1:0.9.git20201127-7
Severity: important
Tags: upstream
User: debian-hurd@lists.debian.org

Hello,
When hurd dumps a core file it cannot be read properly in gdb. This is
either due to a bug in the Hurd package itself or a bug in gdb. The
core dump code in Hurd seems to be located at:
exec/elfcore.s:dump_core().
I'm filing this bug to Hurd, but the problem might also be in gdb not
being able to read the core file.
Example session:
host ftp.sunet.se
ftp.sunet.se is an alias for sunet.ftp.acc.umu.se.
sunet.ftp.acc.umu.se has address 194.71.11.173
sunet.ftp.acc.umu.se has address 194.71.11.165

A bug report to the bind9-host package,1:9.16.13-1, will be filed
separately. Probably this is also a Hurd bug and should be assigned to
Hurd, not bind9-host. Some more investigations are needed until then.
Thanks!
