[Bug 1818884] [NEW] gdb versions greater than 8.2.50 don't always respect solib-search-path

[Brian Murray]

Public bug reported:

apport-retrace utilizes gdb in a sandbox and sets multiple configuration
options so that is possible to retrace crashes from an operating system
other than that in which the crash occurred. This was working great
until gdb version 8.2.50.20190213-0ubuntu1 became available for disco.
Here's an example of the gdb command used:

Calling gdb command: '/srv/vms/apport-sandbox-dir/Ubuntu 19.04/amd64
/report-sandbox/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2' '/srv/vms
/apport-sandbox-dir/Ubuntu 19.04/amd64/report-sandbox/usr/bin/gdb' --ex
'set debug-file-directory /srv/vms/apport-sandbox-dir/Ubuntu 19.04/amd64
/report-sandbox/usr/lib/debug' --ex 'set solib-absolute-prefix /srv/vms
/apport-sandbox-dir/Ubuntu 19.04/amd64/report-sandbox' --ex 'add-auto-
load-safe-path /srv/vms/apport-sandbox-dir/Ubuntu 19.04/amd64/report-
sandbox' --ex 'set solib-search-path /srv/vms/apport-sandbox-dir/Ubuntu
19.04/amd64/report-sandbox/lib/x86_64-linux-gnu' --ex 'set data-
directory /srv/vms/apport-sandbox-dir/Ubuntu 19.04/amd64/report-
sandbox/usr/share/gdb' --ex 'file "/srv/vms/apport-sandbox-dir/Ubuntu
19.04/amd64/report-sandbox//usr/bin/gnome-calculator"' --ex 'core-file
/tmp/apport_core_hj0ttq6p'

With the new versions of gdb multiple shared object libraries are no
longer loaded when analyzing the same crash file. I'll add the
differences as comments.
