Actually, that was bug 1728574

But still voting "needs fixing" as the following test is failing on artful:

Mir-on-Mir

Use an X11 based desktop (Unity, Gnome, etc.). These tests run for a default 10 seconds.
Start two terminal sessions, one for a "host" server, one to launch the tests.

Start a "host" server: $ mir_demo_server --window-manager system-compositor
Test that S/W rendering clients run and can be moved(resized) with Alt+Left(Middle)-Button:

...

$ mir_demo_server --no-file --host $XDG_RUNTIME_DIR/mir_socket --test-timeout 10 --test-client mir_demo_client_egltriangle

When resizing the triangle, the nested server crashes. (Doesn't happen with the same code built for Zesty.)

Mmm, this happens with 0.28.0 too.

What was different when testing 0.20.0? It was shortly before the Artful releasee and my laptop had been upgraded to Artful (and had U7 installed). Since then Artful has been released and re-installed on the laptop from an ISO image.

--Tracking ABI compatibility {#abi_compatibility_tools}
--================================
--
--A few make targets exist to help us track ABI compatibility across
--different Mir versions and ensure we increase the ABI version properly.
--These targets invoke the abi-compliance-checker tool for the actual ABI check.
--
--The targets are:
--
--* **make abi-check**
--
--  Compiles all the public libraries in the current tree and checks their ABI against the latest released archive version
--
--* **make abi-check-\<library>**
--
--  Compiles only the specified library in the current tree and checks its ABI against the latest released archive version
--
--  - *library* can be any of the public library targets such as mirclient, mirserver, mirplatform, mircommon, etc.
--
--Sample usage
--------------
--
--    $ bzr branch lp:mir && cd mir
--    $ debian/rules override_dh_auto_configure
--    $ cd <build-dir>
--    $ make abi-check

++Getting Mir source & dependencies
++---------------------------------
++###  On Ubuntu
++
++These instructions assume that you’re using Ubuntu 16.04LTS or later.
++
++You’ll need a few development tools installed:
++
++    $ sudo apt install devscripts equivs bzr
++
++With these installed you can checkout Mir and get the remaining dependencies:
++
++    $ bzr branch lp:mir
++    $ sudo mk-build-deps -i

++### On Fedora
++
++You’ll need some development tools and packages installed:
++
++    $ sudo dnf install bzr cmake gcc-c++ boost-devel mesa-libEGL-devel \
++    mesa-libGLES-devel glm-devel protobuf-lite-devel protobuf-compiler \
