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

[Brian Murray]

This is with gdb version 8.2.1-0ubuntu1 in the sandbox.

(gdb) show solib-search-path
The search path for loading non-absolute shared library symbol files is /srv/vms/apport-sandbox-dir/Ubuntu 19.04/amd64/report-sandbox/lib/x86_64-linux-gnu.

(gdb) info sharedlibrary

Title:
  gdb versions greater than 8.2.50 don't always respect solib-search-
  path

Status in gdb package in Ubuntu:
  New

Bug description:
  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.
